Title:
  systemd tools fail to mount disk images with btrfs filesystems

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Noble:
  Fix Released

Bug description:
  SRU Justification

  [Impact]

  In Ubuntu Noble, systemd-repart fail to mount images with btrfs
  filesystems in them. This is because the kernel removed the
  "norecovery" mount option which systemd-repart adds in when mounting
  filesystems from disk images.

  Commit which removed "norecovery" in the kernel:
  https://github.com/torvalds/linux/commit/a1912f712188291f9d7d434fba155461f1ebef66.

  [Fix]

  The issue was worked around upstream in systemd in
  https://github.com/systemd/systemd/pull/32892 and
  https://github.com/systemd/systemd/pull/32948.

  [Test]

  To reproduce:

  git clone https://github.com/systemd/mkosi
  cd mkosi
  bin/mkosi -d fedora -t disk --tools-tree=default -f
  sudo systemd-repart --image mkosi.output/image.raw
  The last command will fail with "Failed to mount image: Invalid argument". After backporting the two systemd commits, the last command will succeed.

  [Regression Potential]

  Low, the systemd commits only change behavior for btrfs filesystems,
  which are currently not working at all. The commits have been
  backported to the systemd stable releases and we've had no reports of
  any issues caused by backporting these commits.
