# The mdadm RAID1s were created with 'mdadm --create ... --homehost=hetzner',
# but the hostname for each machine may be different, and mdadm's HOMEHOST
# setting defaults to '<system>' (using the system hostname).
# This results mdadm considering such disks as "foreign" as opposed to
# "local", and showing them as e.g. '/dev/md/hetzner:root0'
# instead of '/dev/md/root0'.
# This is mdadm's protection against accidentally putting a RAID disk
# into the wrong machine and corrupting data by accidental sync, see
# https://bugzilla.redhat.com/show_bug.cgi?id=606481#c14 and onward.
# We do not worry about plugging disks into the wrong machine because
# we will never exchange disks between machines, so we tell mdadm to
# ignore the homehost entirely.
