@ddstreet I'm not sure where upstream is going just yet. For Ubuntu; I think
1) Adjusting the bcache-tools patch to use the full path to bcache- super-show should change; 2) If we fix (1) then I think we can drop the systemd patch from a bug fixing perspective; on the openSUSE image I did testing on; the skip of the dev/disk/by-uuid symlink for backing devices does not *break* the /dev/bcache/by-uuid ; it was missing due to the updated 69-bcache.rules not working. 3) IMO, blkid should not report FS_UUID for bcache backing/cache devices since it's not a Filesystem; we could patch that in blkid directly instead; alternatively since older blkid's may or maynot emit FS_UUID for bcache backing/caching devices the patch to systemd we're caring will avoid creating a useless dev/disk/by-uuid symlink to those devices. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Triaged Status in linux package in Ubuntu: Incomplete Status in linux-signed package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Fix Released Status in bcache-tools source package in Bionic: New Status in linux source package in Bionic: New Status in linux-signed source package in Bionic: New Status in systemd source package in Bionic: New Status in bcache-tools source package in Focal: Confirmed Status in linux source package in Focal: Invalid Status in linux-signed source package in Focal: Confirmed Status in systemd source package in Focal: Confirmed Status in bcache-tools source package in Groovy: Triaged Status in linux source package in Groovy: Incomplete Status in linux-signed source package in Groovy: Confirmed Status in systemd source package in Groovy: Fix Released Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
