* Output from systemd -
sudo systemctl --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
● zfs-import-scan.service loaded failed failed Import ZFS pools by device
● 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.
1. Grab a stock xenial image, and unpack it and add zfs-utils to it. Repack
2. Boot machine
3. Check systemctl --failed.
* none expected, patch has been intensively tested by the upsteam zfs
test script suite.
* This is a upstream commit merge in 0.7.0.
* A ubuntu package has been tested (including the upstream commit) by
a user of the community facing this bug, and confirmed it addresses
the problem (see comment #7).
* The "reading" is redirected to /proc/self/mounts.
The writing to /etc/mtab. Some distros still need that. The current hope is
to replace the writing (and maybe reading) with libmount, in a second phase.
