Thanks for the quick upload, Valentin!  I kept triggering CI runs until
one finally failed again, but didn't have the time to actually look at the
logs.  Udev losing the race against dpkg configuring a bunch of packages
is rather unexpected, but apparently can happen from time to time.  We
were probably bitten by https://github.com/systemd/systemd/issues/2913
here; what do you think about saving the full journal as a test artifact
in case anything similar crops up in the future?
