For me the issue also appeared with 229-4ubuntu21.9. Was fixed with
229-4ubuntu21.10 and now appeared again with 229-4ubuntu21.15. I'm on
Armbian with ext4 and have the issue now again.

Title:
  systemd-tmpfiles-setup.service fails on btrfs

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Bionic:
  Fix Released
Status in systemd source package in Cosmic:
  Fix Released
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...
  Nov 21 13:44:12 node-blc49 systemd-tmpfiles[1226]: Failed to create directory or subvolume "/var": Bad file descriptor
  Nov 21 13:44:12 node-blc49 systemd-tmpfiles[1226]: Failed to create directory or subvolume "/home": Bad file descriptor
  Nov 21 13:44:12 node-blc49 systemd-tmpfiles[1226]: Failed to create directory or subvolume "/srv": Bad file descriptor
  Nov 21 13:44:12 node-blc49 systemd[1]: systemd-tmpfiles-setup.service: Main process exited, code=exited, status=1/FAILURE

  Nov 21 13:44:12 node-blc49 systemd[1]: Failed to start 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.
