Hello Valentin, or anyone else affected, Accepted systemd into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/249.11-0ubuntu3.12 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-jammy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: systemd (Ubuntu Jammy) Status: New => Fix Committed ** Tags added: verification-needed verification-needed-jammy -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/2037281 Title: Shutdown when triggering daemon-reload early in boot Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Focal: New Status in systemd source package in Jammy: Fix Committed Bug description: In Ubuntu Core 20, and Ubuntu Core 22, we are encountering an issue where if a service, started earlier than devices are processed by udev, does `systemctl daemon-reload`, the system shuts down. This is due to devices for mounted filesystem temporarily taken dead, which pulls most units down. This was fixed by upstream in https://github.com/systemd/systemd/pull/23218. But this was not backported to the versions used by Ubuntu packages for focal and jammy. The needed commit from that PR is the one with message `core/device: ignore DEVICE_FOUND_UDEV bit on switching root`. This patch applies to 245.4-4ubuntu3.22 (focal) without rebasing needed. And I suppose it does also for jammy. I have manually tested the fix with Ubuntu Core 20, and this fixes our issue. We would like this patch to be backported to focal-updates and jammy- updates. Thank you in advance. [ Impact ] If a user adds a service that calls `systemctl daemon-reload`, and if this service is started before systemd-udevd. And if the initrd is systemd (the case of Ubuntu Core), then most service will be stopped or cancel, and the machine will mostly shutdown everything and hang. The fix has been backported down to 250 upstream. It is already on kinetic and later. The fix only affects systems where systemd is used in initrd. [ Test Plan ] On Ubuntu Core 20 (with Core 22 kernel) or on Ubuntu Core 22. Or on any system that uses systemd in initrd. Add a systemd service that calls `systemctl daemon-reload`. The service should have `DefaultDependencies=no` in order to start as soon as possible and be enabled. Restart the machine. If fix is not applied, after the service is started, most of units with be shutdown, and the system will be unusable. [ Where problems could occur ] This should affect systems with systemd in initrd. There are risks on systems that have an udev rule in initrd not present in the main system. There are risks on systems that use db_persist in initrd where the device can potentially get dead state. Though this does not seem to happen on Ubuntu Core 22, even though we use db_persist for dev mapper devices. Regression is upstream bug #23429. Commits named "core/device: device_coldplug(): don't set DEVICE_DEAD" and "core/device: do not downgrade device state if it is already enumerated" could be applied as well.
