[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).
