I've got two systems that report a failure (exit code 1) every time systemd-gpt-auto-generator is run. There are a small number of reports of this affecting other users too:
https://bugs.archlinux.org/task/73168 This *may* be related to the use of ZFS, although I've got a half-dozen systems using ZFS and only two of them have this issue. Running the generator from the command line also produces exit code 1, but doesn't produce any output. is there any practical way to debug this failure?
