The logic to detect disks via /proc/partitions didn't cover NVMe disks,
as the regex '[a-z]$' fails for the "nvme0n1" pattern:
| % cat /proc/partitions
| major minor #blocks name
|
| 259 0 500107608 nvme0n1
| 259 1 524288 nvme0n1p1
| 259 2 499582279 nvme0n1p2
| [...]
| 8 0 384638976 sda
| 8 1 384606208 sda1
Instead, let's use lsblk to detect present disks, which works
fine for all kinds of disks, incl. NVMe devices.

If grml-debootstrap detects an existing FAT filesystem on the EFI partition,
it doesn't modify/re-create it:
| EFI partition /dev/nvme0n1p2 seems to have a FAT filesystem, not modifying.
The underlying check is execution of `fsck.vfat -bn $DEVICE`.
Now with fsck.fat from dosfstools v4.1-2 as present in Debian/buster we got:
| root@grml ~ # fsck.vfat -bn /dev/nvme0n1p2

When we run current versions of deployment.sh, which include the fix
from commit f9aea18c, in combination with grml-debootstrap <=0.96 (as
shipped by our Grml deployment ISO version sipwise20210511), deployments
using EFI might fail with:
| Mounting /dev/nvme0n1p2 on /boot/efi
| Invoking efibootmgr
| EFI variables are not supported on this system.
| -> Failed (rc=1)
| [...]
| Mounting /dev (via bind mount)
| Mounting efivarfs on /sys/firmware/efi/efivars
| Invoking grub-install with proper EFI environment
| chroot: failed to run command 'grub-install': No such file or directory
| -> Failed (rc=127)
This is caused by a failing invocation of efibootmgr from within
grml-debootstrap (versions <=0.96 and running with Debian kernel
>=5.10), causing grml-debootstrap to exit then. As a result, the EFI
specific GRUB steps in grml-debootstrap's grub_install() from within
chroot-script doesn't get executed. Therefor the grub-efi-amd64 package
is missing for usage by our efivarfs post-script.
By re-introducing the efivarfs pre-script from commit 535e6df3
we can work around this bug.
Furthermore, when /boot/efi should be mounted within the target system
by our efivarfs post-script, it might fail when /proc isn't available, like:
| # chroot /mnt mount /boot/efi
| mount: /boot/efi: can't find UUID=FE60-5B75.
This can be fixed by ensuring to mount /proc, /sys etc *before*
/boot/efi. Then scanning for the UUID device (as configured in
/etc/fstab) works as expected.
While at it fix a comment regarding grml-debootstrap >=v0.97 vs >=v0.99,
as only v0.99 behaves as expected with our EFI requirements.

This is a followup fixup for commit 535e6df / Change-Id: I5374322cb0a39cfed6563df6c4c30f1eafe560c1
We had to apply fixes due to efivars vs efivarfs in kernel versions
>=5.10, and addressed them in commit 535e6df. Those changes were
incomplete though, as the fix included in grml-debootstrap v0.97 is
incomplete: while efibootmgr was properly invoked and working,
invocation of grub-install doesn't reliably work (as at that time
/sys/firmware/efi/efivars is no longer accessible). GRUB installation on
EFI systems without /sys/firmware/efi/efivars present warns with "EFI
variables are not supported on this system" (see
https://sources.debian.org/src/grub2/2.04-20/debian/patches/efi-variable-storage-minimise-writes.patch/?hl=650#L650),
though returns with exit code 0. This leaves us with an incomplete and
therefore not booting GRUB EFI environment.
This used to work with mr9.5.1 only, because there we install(ed)
systems using grml-debootstrap v0.96, which is *older* than the version
v0.97 (which included the EFI workaround) we check for in deployment.sh.
Since the grml-debootstrap version v0.96 isn't recent enough there, we
applied the fallback to our local scripts, which took care of proper
installation of GRUB in EFI environments.
On the other side, in recent trunk deployments we have grml-debootstrap
v0.98 available, which includes the EFI workaround - therefore our local
scripts aren't applied. The resulting installation is incomplete, and
recent trunk deployments fail to boot in EFI environments.
The according fix for grml-debootstrap has been made and is going to be
released in the next few days as v0.99. But to ensure that it's working
also with older grml-debootstrap versions (and we don't have to rebuild
our squashfs environments), the local scripts have been adjusted.
We don't even need any pre-script at all, instead we handle all of the
GRUB EFI installation through /etc/debootstrap/post-scripts/efivarfs.
FTR: this issue didn't show up on certain test systems of us, because
SW-RAID is used there. In deployment.sh we have special handling
of SW-RAID regarding efibootmgr and grub-install, see line 2330 ff.

Jobs like daily-build-matrix-debian-boxes build plain Debian machines,
not NGCP-based ones. At the moment we're generating the udev-rules for
network renaming unconditionally, so we have to do it consistently,
either both conditionally and not for "plain" systems, or both
unconditionally, so network can be brought up by a correct
/etc/network/interfaces after the devices are brought up with the new
names.
There is a good-ish argument for keeping using eth0, as it is more of a
default, but we're already deviating from the default for several years
and Debian stable releases by having these names and not ones like
"ens18" or "enp4s0f2" which is the default in Debian nowadays, at least
since buster.
So it is probably better to keep it consistent with our other machines
and use "neth*" naming for those too.
Change-Id: I6b3b49a1769894580df768abb817ae5196e65963
The code removed was enabled when $VAGRANT=true, and this happened when
passing "vagrant" parameter to deployment.sh, which is done in places
like proxmox-vm-clone job, the base of many of our tests machines.
VMs do not necessarily have the same hardware configuration, so removing
udev-rules for network devices makes sense in principle. Especially
when since the beginning we were using network devices named "eth*"
everywhere, even if in the last years we had to use net.ifnames=0 and
udev-rules files in hardware to keep using "eth*" names.
However, now with mr9.5 and the move to Debian bullseye we have to start
using different names, and we settled on the direct translation to
"neth*". So we need a way to assign whatever network devices the
machines come with, including VMs, to names "neth*".
(If we used the new-permanent device names like ens18 or enp3s0f1 we
would have to adapt network.yml and files like network interface, and
they would be different across all the different machines (HW and VM) so
this is not a better or faster solution to the problem.)
So, back to the topic of removal of this udev-rules file: in many cases
in our test infra, the machines are built "in place" and then rebooted
for upgrades or tests, in princicple with the same hardware
configuration, so there is no need to remove these files.
In cases where the underlying (virtualized) hardware changes, e.g. to
use like local VirtualBox-based vagrant machines, we will need to adapt
the rules for the existing devices.
Change-Id: I57e39a2ec6849f3b5bb8f6cf518e2a2923ec19cb
Using "eth*" names was discouraged for many years, we've been finding
problems here and there and working around them with the help of
udev-rules (/etc/udev/rules.d/70-persistent-net.rules) to map address
interfaces according to PCIIDs, using "net.ifnames=0" as Linux kernel
boot parameter when booting in GRUB, etc.
Finally we found unsurmountable problems when moving to Debian bullseye
(mr9.5), because as we attempt to rename interfaces in some hardware
systems that we use, we got race conditions and clashes with renaming
that we could not solve in other ways.
We had different alternatives:
- Use names purely deterministic, based on PCI paths (for example
"enp4s0f1"), MAC address or other of the alternatives, which would be
"definitive", but given that we have a diversity of hardware and VM
installations in customers the devices in different systems would be
different, and the fact that it would be easier to mistype or confuse
them makes this not ideal.
- Use names purely based on functionality, like for example "ha0",
"ext0" or "int0". The problem in this case is that we would have to
find names that would satisfy everyone (and there's no time for doing
this at this point), that different of our system types are quite
different (e.g. Pro without bonds, Carrier with bonds and many vlans
by default; using the same hardware), and some customers with
different installations or needs (e.g. using VMs) have also totally
different network configuration -- so any attempt to unify this to
make good use of the functionality-based names would be very
challenging.
- Finally, there's the option to use some symbolic names similar to
traditional names like "eth0", but without being exactly this.
Popular names in general, although there's no wide consensus, are
names like "net0" and "lan0".
Talking with groups involved in deploying and maintaining the system,
the decision was taken to move to names not purely deterministic, and
there's no time for purely symbolic (they also didn't express much
interest on them), and prefer something more traditional that they are
already used too. Instead of names like "net0" or "lan0", they prefer
the more direct mapping to existing interfaces like "neth0".
This is ugly or slighly discomforting to use for some, but since the
main users (among us) of these names prefer them, so be it. It has the
advantage of having a very simple and mechanichal translation based on
the current names, which is an advantage especially at the critical time
of upgrading existing systems to the new name.

This is commit cd50e4934c applied again.
As explained in ab62171c49, the original
change had to be reverted because even if things work perfectly fine, in
the case of Vagrant machines (or when passing "vagrant" parameter to the
script) the udev-rules for persistent-net devices get removed, so then
the network interfaces get "random" names and the configuration in
/etc/network/interfaces doesn't match, the network is not brought up.
This removal happens in the case of {ce,pro,carrier}-trunk.mgm machines
of our tests, which shouldn't be needed, and also in the images created
for Vagrant machines, which is understandable because the machines could
be brought up with different PCIIDs in different versions of VirtualBox,
or due to some other difference -- not sure how we can ensure that the
PCIIDs as written in the udev-rules files will work in that case.
But in principle this change must go ahead when we solve these problems,
so submitting it again to be ready.

Run the installer under "eatmydata" to speed up the process. Also add
some more information about timing.
In some VMs that we install daily ({ce,pro,carrier}-trunk.mgm) we have
the following timings:
ce-runner, no eatmydata:
162 seconds, 2 mins 42 secs
ce-runner, with eatmydata:
142 seconds, 2 mins 22 secs
pro-runner, no eatmydata:
246 seconds, 4 mins 06 secs
pro-runner, with eatmydata:
217 seconds, 3 mins 37 secs
So in these machines, for CE we save about 20 seconds, which is not much
in total but it's about 12.5% saving; and in Pro about 30 seconds (and
twice, once per machine, so about a minute in total), which is about
12.2% as well.
In Carrier, which is mostly equivalent to Pro in this respect and
typically at least 8 machines, it would mean about 4 mins in total.
When installing in hardware in previous days, maybe due to the disks
being slower, the total installation time was slightly slower:
pro-hardware (Lenovo ThinkSystem SR250), with eatmydata:
226 seconds, 3 mins 46 secs
Installing without eatmydata was not measured yet in hardware, but given
that the time to install is similar to the case of pro-runner, probably
the performance gain is similar too.
This looks like a relevant saving, the risk of things going wrong are
minimal, so enable it by default.

This reverts commit cd50e4934c.
In principle this works fine when using
/etc/udev/rules.d/70-persistent-net.rules, but it turns out that in the
test infrastructure (including {ce,pro,carrier}-trunk.mgm machines and
build-matrix) we remove the generated rules in many places:
if $VAGRANT; then
...
# MACs are different on buildbox and on local VirtualBox
# see http://ablecoder.com/b/2012/04/09/vagrant-broken-networking-when-packaging-ubuntu-boxes/
echo "Removing '${TARGET_UDEV_PERSISTENT_NET_RULES}'"
rm -f "${TARGET_UDEV_PERSISTENT_NET_RULES:?}"
So in this way, the interfaces that we get are ens18 in our infra for
{ce,pro,carrier}-trunk.mgm machines, and so the generated
/etc/network/interfaces usint the fixed names "eth*" (in process to be
renamed "neth*") cannot be found in those systems, and all
build-install-vm jobs fail.
In a local vagrant machine (ce-trunk from just before the change) we
have names like these for the network devices:
root@spce:~# dmesg | grep rename
[ 2.051263] e1000 0000:00:09.0 enp0s9: renamed from eth1
[ 2.065876] e1000 0000:00:03.0 enp0s3: renamed from eth0
[ 3.950540] e1000 0000:00:03.0 eth0: renamed from enp0s3
[ 4.049842] e1000 0000:00:09.0 eth1: renamed from enp0s9
In this boot session from which the logs above are taken, was booted
with grub without "net.ifnames=0", and udev "70-persistent-net.rules"
generated in place with the right infromation, and then of course things
work fine.
So we need some solution this before moving on with the change now
reverted.

Current trunk installations based on bullseye using recent Grml
environments are broken, as EFI environments running with recent kernel
versions (>=5.10) aren't properly detected anymore.
This is caused by the missing efivars kernel module.
CONFIG_EFI_VARS is no longer available since
20146398c4
(tagged initially as debian/5.10.1-1_exp1 + shipped with kernel package
5.10.1-1~exp1 and newer, incl. 5.10.38-1 as present in current
Debian/unstable). Therefore the kernel module efivars is no longer
available on more recent Debian kernel systems.
Quoting from https://wiki.debian.org/UEFI:
| The older interface was efivars, showing files under
| /sys/firmware/efi/vars, and this is what was used by default in both
| Wheezy and Jessie.
|
| The new interface is efivarfs, which will expose things in a slightly
| different format under /sys/firmware/efi/efivars. This is the new
| preferred way of using UEFI configuration variables, and Debian switched
| to it by default from Stretch onwards.
CONFIG_EFI_VARS is no longer required, instead efivarfs seems to be
available starting with kernel v3.10 and newer (see linux.git):

| efivarfs: Move to fs/efivarfs
|
| Now that efivarfs uses the efivar API, move it out of efivars.c and
| into fs/efivarfs where it belongs. This move will eventually allow us
| to enable the efivarfs code without having to also enable
| CONFIG_EFI_VARS built, and vice versa.
|
| Furthermore, things like,
|
| mount -t efivarfs none /sys/firmware/efi/efivars
|
| will now work if efivarfs is built as a module without requiring the
| use of MODULE_ALIAS(), which would have been necessary when the
| efivarfs code was part of efivars.c.
But we also need to ensure /sys/firmware/efi/efivars is mounted,
otherwise efibootmgr fails to execute:
| # efibootmgr
| EFI variables are not supported on this system.
| # lsmod| grep efi

FTR: we can't test only for existence of directory
/sys/firmware/efi/efivars, as it exists but is empty by default, so we
need to look inside the directory instead.
See https://github.com/grml/grml-debootstrap/pull/174 for the related
grml-debootstrap upstream change, which is supposed to be released as of
grml-debootstrap v0.97.
But as a) grml-debootstrap v0.97 isn't released yet, b) it's unclear
whether grml-debootstrap v0.97 will make it into bullseye (soonish, or
if at all) and c) we don't have the Grml repositories available via our
approx Debian mirror (as used in our PRO/Carrier environments) and don't
want to update our Grml squashfs system for this change neither, we need
to apply a workaround for this efivars vs efivarfs situation. Otherwise
Debian installation fails in EFI environments using Debian kernel
>=5.10. Thankfully we can work around this using according pre/post
scripts in grml-debootstrap, that's what efivars_workaround() is all
about.

Quoting from "man bash" about `-E` (AKA errtrace):
| If set, any trap on ERR is inherited by shell functions, command
| substitutions, and commands executed in a subshell environment.
| The ERR trap is normally not inherited in such cases.
To demonstrate the problem see this short shell script:
| % cat foo
| set -eu -o pipefail
|
| bailout() {
| echo "Bailing out because of error" >&2
| exit 1
| }
| trap bailout 1 2 3 6 9 14 15 ERR
|
| foo() {
| echo "Executing magic"
| magic
| }
|
| foo
| echo end
If "magic" can't be executed, then this fails as follows:
| % bash ./foo
| Executing magic
| ./foo: line 11: magic: command not found
But it doesn't invoke the bailout function via trap.
When using `set -eE` (AKA errexit + errtrace), instead of only
`set -e` (errexit), then it behaves as expected though:
| % bash ./foo
| Executing magic

When running in EFI mode, it's as simple as executing "fwsetup".

This pretty much never works for me, while exiting GRUB switches to the
next device in the boot order, so let's just "exit" GRUB and name the
menu entries accordingly.

grml-live v0.38.0 is the current release, including a change to use 1m
block size for squashfs, which reduces ISO size (see
fada6dea0f),
improvements to EFI, GRUB, documentation and several bug fixes.

grub-pc >=2.04-11 has a new behavior regarding /boot/grub/i386-pc/
handling, where we end up with an empty /boot/grub/i386-pc/ after
*successful* grub-install execution:
| root@grml ~ # vgchange -ay
| 3 logical volume(s) in volume group "ngcp" now active
| root@grml ~ # mount /dev/mapper/ngcp-root /mnt
| root@grml ~ # grml-chroot /mnt /bin/bash
| Writing /etc/debian_chroot ...
| (spce)root@grml:/# cd
| (spce)root@grml:~# grub-install /dev/sda
| Installing for i386-pc platform.
| Installation finished. No error reported.
| (spce)root@grml:~# ls -la /boot/grub/i386-pc/
| total 16
| drwxr-xr-x 2 root root 12288 Dec 16 12:04 .
| drwxr-xr-x 4 root root 4096 Dec 16 12:07 ..
This causes the installed system to fail to boot with:
| GRUB loading..
| Welcome to GRUB!
|
| error: file `/boot/grub/i386-pc/normal.mod' not found.
| grub rescue> _
The underlying issue is that recent grub versions unlink the files
inside /boot/grub/i386-pc, though it doesn't report anything about it
(even under `--verbose` execution).
This is triggered in our situation, as lvm2's vgs binary isn't present
yet. In earlier versions of grub this wasn't causing any problems and
grub-install happily installed the files inside /boot/grub/i386-pc, even
though we installed lvm2 only afterwards via our metapackages. To
ensure lvm2 is available during installation time within
grml-debootstrap, explicitly add to it list of packages to be installed.
See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977544 for further
details regarding the grub bug.

We install virtualbox-guest-additions in the target system for usage
with VirtualBox and shared folders via Vagrant. We invoke the
VBoxLinuxAdditions.run machinery from the running Grml live system. But
the target systems usually has a different kernel package and version
installed, so we have to apply some tricks to get it working. This is
where we rely on fake-uname.so.
Since commit a91baa2 (TT#48647 Ship fake_uname lib in package) we're
relying on fake-uname.so from ngcp-deployment-scripts, instead of
building and shipping it via deployment.sh itself.
But we have ngcp-deployment-scripts available only when installing NGCP
- as we're installing it there and only afterwards invoke
vagrant_configuration() - whereas it's missing when we install a plain
Debian system (like with our debian_bullseye_plain_vagrant.box),
therefore failing with:
| cp: cannot stat '/mnt/usr/lib/ngcp-deployment-scripts/fake-uname.so': No such file or directory
| ERROR: ld.so: object '/usr/lib/ngcp-deployment-scripts/fake-uname.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

The ensure_packages_installed function ensures that specified packages
are present during runtime. This is used e.g. for installation of
virtualbox-guest-additions-iso Debian package from within
vagrant_configuration(), which is used to execute
/media/cdrom/VBoxLinuxAdditions.run inside the target system.
We can't use random Debian repositories though, as the package
dependencies need to match the running live system. So far we only used
the buster repository, as our current grml-sipwise ISOs are based on
something close to buster.
On the other hand we can't use virtualbox-guest-additions-iso from
Debian/buster in our Debian/bullseye Vagrant boxes, as
/sbin/mount.vboxsf doesn't work then.
So use the bullseye repository if the release of the target system is
bullseye, which seems to work with our current Grml ISOs and current
state of bullseye.

Nowadays we only deploy stretch + buster based Debian systems, so drop
those release specific checks to also support bullseye and newer Debian
releases.

grml2usb v0.18.1 included a regression that caused us to revert to
grml2usb v0.17.0 in commmit 9fbc9afeda.
The according fix for our needs is
657b880f02
and was released as v0.18.2
grml2usb v0.18.3 supports Grml's new Secure Boot approach and switches
in grml2iso from isohybrid to xorriso/isohybrid to properly support EFI
boot, besides some further code cleanups, docs improvements and
bugfixes.
Change-Id: I0ce25d05825767120144315f07ded2c66bfffc0f
This is revert of commit aadbef82b0
The version 0.18.1 fails during the building of mr8.5.1:
===============================
10:59:57 Executing grml2usb version v0.18.1 (git)
10:59:57 Checking for boot flag
10:59:57 Fatal: /tmp/grml2iso.tmp/cddir: unrecognised disk label
===============================
So restore working 0.17.0 version.
