- Rather than having one script per fix, use a single script (or "fixlet") per

(sub) package that contains all the fixups relative to a (sub) package. This
  has the advantage to limit the number of scripts but more importantly it will
  ease the sharing of the spec file between TW and SLE. We should also be able
  to compare the fixlets of two distros even if the spec files have diverged.
  Note that all the fixups are run just once now.

# the system we're running on is using BTRFS with the specific layout
# used by snapper to perform snapshots, rollbacks, etc...

# Unfortunately some distros (TW) already shipped versions with
# systemd creating a plain subvolume which breaks snapper.
#
# If /var/lib/machines is already populated then it's going to be
# pretty ugly to convert the old subvolume into a new one specially
# since it can be in use.
#
# Hopefully not a lot of users are using machinectl to import
# container/VM images. So in most of the cases this directory should
# be empty and we can then simple delete the subvolume and create a
# new one respecting the snapper layout.
#
# In the rare case where /var/lib/machines is populated, we will warn
# the user and let him fix it manually.
