With regard to the translation ....
The commit has been intensively tested in different scenarios/env/...
and of course with the "ZFS Test Suite"[1] which include functionality,
perf, and stress tests.
All the tests were reported as successful.
I hope this answer your questions and addresses your concern.
Let rlaager and I know if you need more clarifications.

Bug description:
[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]
* 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).
[Other Info]
* 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.
* Upstream commit : https://github.com/zfsonlinux/zfs/commit/792517389fad5c495a2738b61c2e9c65dedaaa9a
* Upstream bug: https://github.com/zfsonlinux/zfs/issues/4680
* Debian bug : https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=839071
