Git doesn't track file permissions (except for the executable
flag). For sensitive data (like the 'ssl' directory and file
'constants.yml' with passwords included) we've to prevent
non-root users from accessing those files.

hooks/pre-commit is inspired and based on the implementation
as present in etckeeper (and luckily we're license compatible)
and takes care of storing the file permissions inside file
/etc/ngcp-config/.ngcpcfg_perms.

The restore-permissions helper script takes care of restoring the
permissions after cloning the ngcpcfg repository via ngcpcfg
itself (being actions decrypt, pull (PRO-only) + initialise
(PRO-only)). It can be executed manually as well via
`usr/share/ngcp-ngcpcfg/helper/restore-permissions /etc/ngcp-config/`
(or wherever the according ngcpcfg repository is placed at).

Regarding the commit integration: git(1) itself doesn't track
file permissions, so we can't detect changes to file permissions
using git itself. Our new pre-commit hook records file
permissions via the .ngcpcfg_perms file. Now by just invoking it
during 'ngcpcfg commit' time we can ensure that even if there
have been any file permission changes in the working directory
the file .ngcpcfg_perms is then up2date and committed.

JFTR: The solution via the git pre-commit hook ensures that no
matter whether you're using 'ngcpcfg commit …' or  'git commit …'
you always get the file permissions handled via .ngcpcfg_perms.
Now if you want to change file permissions in a clean working
directory and commit *without* using 'ngcpcfg commit' but
directly via git itself then you've to use 'git commit
--allow-empty ...' and thanks to the pre-commit hook the file
.ngcpcfg_perms will still be up2date.
