Subject: libpam-zfs: fails to unload and unmount homedir on exit from graphical session

Date: Thu, 11 Jan 2024 21:06:21 +0100

[Message part 1 (text/plain, inline)]

Package: libpam-zfs
Version: 2.2.2-3
Severity: normal

Dear Maintainer,

After logging out (as testuser), /home/testuser was still mounted.
Before logging in, it was unloaded and unmounted.

Journal says
  Jan 11 20:59:41 chrust systemd[1]: Started session-33.scope - Session 33 of User testuser.
  Jan 11 20:59:55 chrust lightdm[13290]: pam_unix(lightdm:session): session closed for user testuser
  Jan 11 20:59:55 chrust lightdm[13290]: pam_zfs_key(lightdm:session): zfs_unmount failed with: -1
  Jan 11 21:00:01 chrust lightdm[13484]: pam_zfs_key(lightdm:auth): pbkdf failed
  Jan 11 21:00:12 chrust (sd-pam)[13299]: pam_unix(systemd-user:session): session closed for user testuser

I'm in as default a configuration as I could be (sans setting homes=chrust-zoot/home),
using lightdm as the greeter and i3 as the WM. None of testuser's processes persisted.

Best,
наб

-1 is EPERM. So I suspect this is the same problem as #1028613.
Maybe you can check that out and, if indeed, merge the two bugs?
