> IMO it is out of scope for finalrd to unmount mounts > which can't be cleanly unmounted. Er, this is nonsense. The entire point of finalrd is to ensure we pivot to an initramfs after all other processes have been terminated, so that it is possible to cleanly unmount the root filesystem with no errors. For the root filesystem to be busy and failing to unmount is clearly a bug in either systemd or finalrd. ** Changed in: finalrd (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920107 Title: Failed messages of sd-umount shown with reboot/shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/1920107/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Dimitri, The issue can be reproduced by http://cdimage.ubuntu.com/ubuntu- core/20/stable/current/ubuntu-core-20-amd64.img.xz while I previously fetched the image there to test, so if you think it's snap relevant, I can check with snapd team. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920107 Title: Failed messages of sd-umount shown with reboot/shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/1920107/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1920107] Re: Failed messages of sd-umount shown with reboot/shutdown
The way uc20 is booted, and how bind mounts are setup means that we do force unmount eventually. It matters which snaps are installed, and which processes have memory mapped which files. Many things should probably be marked for lazyunmount. Please provide details why is held up /oldroot/run/mnt/data For example output from fuser. I do not believe any of the linked issues are of relevance here. It matters how snaps have been mounted, as they do get mounted circularly. ** Changed in: finalrd (Ubuntu) Status: New => Incomplete ** Changed in: snapd Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920107 Title: Failed messages of sd-umount shown with reboot/shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/1920107/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
