Public bug reported:
[Impact]
* zfs services fail on firstboot if zfs-utils is integrated into the
deployment image.
* Output from systemd -
sudo systemctl --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
● zfs-import-scan.service loaded failed failed Import ZFS pools by device
scanning
● zfs-mount.service loaded failed failed Mount ZFS filesystems
* This is particularly frustrating for users who use automated
monitoring as it means virtual machines must always be restarted before
showing as clean.
* This failure is due to zfs services starting up before /etc/mtab has
a chance to be symlinked to /proc/mounts.
[Test Case]
1. Grab a stock xenial image, and unpack it and add zfs-utils to it. Repack
it.
2. Boot machine
3. Check systemctl --failed.
[Regression Potential]
*
[Other Info]
* This can likely be resolved in the systemd init scripts, by modifying
zfs-linux to depend on /proc/mounts instead, or inclusion of
/lib/init/mount-functions.sh in initscripts (sysvinit).
