Public bug reported: [Impact]
* finalrd is a useful tool, that improves ability to cleanly shut down systems. It is now desired to backport it all the way back to xenial. On classic systems it will not be installed by default, but available for users to opt-in into having it. On Ubuntu Core systems it will be installed by default, and used instead of snap-shutdown. As finalrd does everything that snap-shutdown already did, and much more. * finalrd is only tweaked slightly in version 6 to be compatible with any systemd from xenial to groovy. [Test Case] Classic * Install finalrd * execute `sudo finalrd` and observe that no stderr is printed, and command exits successfully * check that /run/initramfs is created and populated with /run/initramfs/shutdown, binaries and libraries. * Reboot * Observe that finalrd unit is started ** (optional) to make observing finalrd easier add /etc/finalrd/echo.finalrd hook that does `echo $@` with a sleep * Shutdown, capture console-log observe that finalrd was executed Core * Create custom core, core18 with finalrd preinstalled * Building custom Ubuntu Core 16 and Ubuntu Core 18 image with above core * Observe that finalrd unit is started on boot * Shutdown, capture console-log observe that finarld was executed. * Boot again * execute `sudo finalrd` and observe that no stderr is printed, and command exits successfully * check that /run/initramfs is created and populated with /run/initramfs/shutdown, binaries and libraries. [Regression Potential] * Packaging & tmpfiles were changed to be compatible with older systemd versions. There are no changes to api/abi of the systemd units, or .finalrd hooks. The package is not installed by default on xenial/bionic, hence the number and type of machines affected is small. If regressions are identified, reverting to previous version of the package is safe course of action, as there are no upgrade/downgrade incompatibilities between old & new versions of finalrd. ** Affects: finalrd (Ubuntu) Importance: Undecided Status: New ** Affects: finalrd (Ubuntu Xenial) Importance: Undecided Status: New ** Affects: finalrd (Ubuntu Bionic) Importance: Undecided Status: New ** Affects: finalrd (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: finalrd (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: finalrd (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: finalrd (Ubuntu Xenial) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895160 Title: Backport finalrd 6 to xenial and up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/finalrd/+bug/1895160/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
