Subject: [PATCH] MT#17529 Create partitions using optimal partition table
alignment
parted supports the "-a optimal" option to get better alignment during partition table setup.
We should use that by default, since it:
a) shouldn't cause any harm on VMs anyway and
b) might improve performance especially on SSDs with non-standard
optimal_io_size settings (as observed on a Samsung EVA 850
with a setting of 33553920, so the partition should start
at 33.6MB and not 1MiB/2048s)
NOTE: fai-setup-storage doesn't support setting the parted options
like "-a optimal" yet, reported as #812712 in Debian's BTS.
