Bug#1020312: usrmerge: systemd file disappearing
Le 20/09/2022 à 11:41, Luca Boccassi a écrit : Most of the issues would crop up when actually attempting to move things, Interrupting a running upgrade is always problematic. Lots of packages are then in broken state (half installed). Apt has difficulties to recover from such a situation. Sometimes, it needs additional packages requiring a working network (but network-manager can be broken at this point...) so a dry-run would be a lot of work and provide little benefits I think. The goal of the dry-run would be to be run *before* the upgrade start (with the debconf framework) so that the admin can fix any conflict situation described by your matrix when they still have a working system. The other "solution" is to do an upgrade in two-stage 1) install usrmerge 2) do the real upgrade So, a kind of do-release-upgrade (as Ubuntu has) To be thorough you'd have to replicate the filesystem somewhere else and try it there first, but that requires a huge amount of disk space and a lot of time too, I do not understand this argument. While would we need to replicate the FS? I'm just thinking to explore the FS (/lib, ...) and check there is no conflicts as listed in your matrix. so it doesn't seem worth it, given in 5+ years on multiple distros this is the first case we've seen. I think what we should add is debsums -c before/after, and fail if something is not right, so that there's an immediate and clear error plus recovery step presented. I've sent a patch to Marco for this. debsums is very long to be run on a big system or on a system with old (magnetic) disks. Running it twice would lead to a very long installation time of usrmerge. But I'm glad we figured out what went wrong, as it was a very puzzling case. With my systemd maintainer hat on: you shouldn't move these files away to /etc. Units shipped in /usr|/lib are fixed vendor-provided files, and must not be modified. Local modifications should instead happen on /etc or /run. I strongly advise to fix that on your system. (of course we still need usrmerger to support the generic case, that goes without saying) You do not understand my goal. I never modified files in /etc/conffiles-out-etc/ These are the unmodified file shipped in /lib/systemd/system. My goal in putting them here is that they are tracked by etckeeper, so that I can easily see their modifications during an upgrade. It happens a few times that this help me to quickly revert a change I do not want for my system for the default settings. In this cases, the fix goes to /etc/systemd/system/ as it should. Being able to look at the history of these default configuration files is really a good point for me (hence this change done on several of my machines) Regards, Vincent

Hi, Le 20/09/2022 à 04:22, Marco d'Itri a écrit : Indeed, this should be handled. Let's have a look at the code: [...] In your case the expected outcome should have been a failure instead, because /lib/systemd/system/ was a link which did not point to /usr/lib/systemd/system/ : fatal("Both $n and /usr$n exist"); So yes, I should have been informed before rebooting. My upgrade should have been interrupted. However, I'm not really pleased with the fact that a key package of the upgrade can fail on unusual but valid cases. When it appends in a dist-upgrade, the resulting state is often a mess to recover from (less than the one I suffered, but still really annoying). What about: 1) adding a --dry-mode to /usr/lib/usrmerge/convert-usrmerge that report about conflicts but do not change anything on the FS 2) embedding and using convert-usrmerge in dry-mode from the debconf script. Put a low warning notice if the script fail due to missing dependencies (perl, perl modules, ...) Put a high warning notice if the script detect a conflict This would allows one to stop the conversion in case of strange layout in the FS before the upgrade start. Regards, Vincent

But as it is allowed > to create symlinks to other part of the disk for directory, > usrmerge should handle this case (or, at least, give a > preeminent message about a strange situation) Indeed, this should be handled. Let's have a look at the code: # both source and dest are directories if (-d $n and -d "/usr$n") { # so they have to be merged recursively my $rule = File::Find::Rule->mindepth(1)->maxdepth(1)->start($n); while (defined (my $name = $rule->match)) { convert_file($name, $later); } return; } # both source and dest are links if (-l $n and -l "/usr$n") { ... } # the source is a link if (-l $n) { my $l = readlink($n); return if $l eq "/usr$n"; # and it points to dest fatal("Both $n and /usr$n exist"); } # the destination is a link if (-l "/usr$n") { ... } But -d is true also for a symlink which points to a directory, so the latter blocks are never reached! And running File::Find::Rule this way on a symlink without a trailing / returns no matches: my $rule = File::Find::Rule->mindepth(1)->maxdepth(1)->start('/var/lock'); while (defined (my $name = $rule->match)) { say $name; } So the content of the link target was not moved to /usr, and then the link (/lib/systemd/system/) was just deleted during the final cleanup because at that point only valid links to their counterparts in /usr are supposed to be left in the source directories. In your case the expected outcome should have been a failure instead, because /lib/systemd/system/ was a link which did not point to /usr/lib/systemd/system/ : fatal("Both $n and /usr$n exist"); (Also see the "CONFLICTS RESOLUTION MATRIX" section in the man page.) While this bug is annoying and needs to be fixed, we had not noticed it in many years so apparently it is an highly unusual case. And thankfully no files are lost and they can just be moved manually to the new directory. Now I just need to figure out if the safest solution would be to move the "both source and dest are directories" block at the end or leave it there and make it ignore directories which are links. -- ciao, Marco signature.asc Description: PGP signature

Due to the numerous missing files, I'm sure the problem comes from the apt upgrade. The FS is in a good state (no corruption) with nearly 9GB free (so no out-of-space problem). My system was perfectly booting and working before. Note that usrmerge has really run: I see this package that would be newly installed before starting the upgrade (and I read its bug page and the links to the TC decisions because initially I did not want to merge my /usr).
