Bug#973737: systemd: wtmp not updated after unexpected reboot

[Guy Geens]

Package: systemd
Version: 241-7~deb10u4
Severity: normal

Dear Maintainer,

Recently, I had a power loss on one of my machines.

After the reboot, wtmp contained the following entries:

$ last reboot
reboot   system boot  4.19.0-12-amd64  Tue Nov  3 09:09   still running
reboot   system boot  4.19.0-12-amd64  Mon Oct 19 14:54   still running
reboot   system boot  4.19.0-11-amd64  Sat Sep 26 12:27 - 14:54 (23+02:26)

The previous reboot is still listed as "running", while it should have
been updated.
