# This is used to initially create /var/lib/machines subvolume in case
|
||||
# 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.
|
||||
#
|
||||
# In order to avoid ugly dependencies added in systemd package, this
|
||||
# script should only be called during package updates when
|
||||
# mksubvolume(8) is available. During installation, /var/lib/machines
|
||||
# is supposed to be created by the installer now.
