SRU Justification
[Impact]
In Ubuntu Noble, systemd tools fail to mount images with btrfs filesystems in them. This is because the kernel removed the "norecovery" mount option which systemd tools add in some scenarios 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-dissect -M mkosi.output/image.raw abc
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. |
