Hi everyone,
right now I've got an emergency mode only with 18.04 (kde neon) and
systemd=237-3ubuntu10.9 with btrfs. Is there a patch for 18.04/bionic
that could be tested out? Seems like LTS release has been forgotten
about. Downgrading to 237-3ubuntu10 isn't an option as it breaks ton of
dependencies.
Thanks for any suggestions.

Title:
systemd-tmpfiles-setup.service fails on btrfs
Status in systemd package in Ubuntu:
Fix Released
Status in systemd source package in Bionic:
Confirmed
Status in systemd source package in Cosmic:
Fix Committed
Status in systemd source package in Disco:
Fix Released
Bug description:
[Impact]
* Last security update introduced a regression on btrfs based systems, causing systemd-tmpfiles-setup.service to fail to start, resulting in degraded machines.
* Cherrypick upstream fixes to resolve this.
[Test Case]
* Install VM using btrfs for /
* Boot, check that systemd-tmpfiles-setup.service is started successfully with:
$ systemctl status systemd-tmpfiles-setup.service
[Regression Potential]
* btrfs fd doesn't support the set of flags that systemd used, with
this patch, a compat set of flags is set instead, thus resolving the
introduced regression. The worst case scenario is that creating
subvolumes/directories is still broken (as in, the current status
quo).
[Other Info]
* Example bad output
After update to systemd 237-3ubuntu10.9 systemd-tmpfiles-setup.service fails with:
Nov 21 13:44:12 node-blc49 systemd[1]: Starting Create Volatile Files and Directories...

This happens on btrfs root filesystems in real hardware and on our
virtualized servers as well. 237-3ubuntu10.6 didnt show this errors
and going back to 237-3ubuntu10 removes them as well.
