[Touch-packages] [Bug 1819728] Re: Please backport "fix race between daemon-reload and other commands #8803" to 16.04 (for UC16) and 18.04 (for UC18)
This fix caused a regression in our Dracut-based boot setup. Since this patch was incorporated (237-3ubuntu10.17), some of several of the (PC-type) models we provide to our customers that tend to have "slow I/O", no longer boot because Dracut times out waiting for the root file system to come online because the systemd-crypt@ service can no longer be started. We are currently using a build of this source package that doesn't include this patch to fix this temporarily. I have filed a bug eport at Systemd's GitHub too, this contains more information: https://github.com/systemd/systemd/issues/12371. ** Bug watch added: github.com/systemd/systemd/issues #12371 https://github.com/systemd/systemd/issues/12371 -- 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/1819728 Title: Please backport "fix race between daemon-reload and other commands #8803" to 16.04 (for UC16) and 18.04 (for UC18) Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: Fix Released Status in systemd source package in Bionic: Fix Released Bug description: [Impact] On Ubuntu Core we recently hit the a race in daemon-reload and systemctl twice.

Hello Michael, or anyone else affected, Accepted systemd into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/237-3ubuntu10.17 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 and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. 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. ** Tags removed: verification-failed-bionic ** Tags added: verification-needed-bionic ** Changed in: systemd (Ubuntu Xenial) Status: Triaged => Fix Committed ** Tags removed: verification-failed-xenial ** Tags added: verification-needed-xenial -- 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/1819728 Title: Please backport "fix race between daemon-reload and other commands #8803" to 16.04 (for UC16) and 18.04 (for UC18) Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: Fix Committed Status in systemd source package in Bionic: Fix Committed Bug description: [Impact] On Ubuntu Core we recently hit the a race in daemon-reload and systemctl twice.

Unfortunately we need to pull the xenial update.
