Successful boots which crashed somehow and sometime afterwards, will
show the same "until" value ("still running" or timestamp) as the next
following boot(s). The most recent boot from such a sequence of
duplicated "until" lines, has not been crashed or not yet.
Example output where only the boot from 16:25:41 crashed:
reboot system boot 6.5.11-7-pve Thu Apr 11 16:31:24 2024 still running
reboot system boot 6.5.11-7-pve Thu Apr 11 16:29:17 2024 - Thu Apr 11 16:31:12 2024 (00:01)
reboot system boot 6.5.11-7-pve Thu Apr 11 16:25:41 2024 - Thu Apr 11 16:31:12 2024 (00:05)
...
Furthermore, it shows the booted/crashed/problematic kernel version.
`last` is also used since currently `journalctl --list-boots` can take
10 seconds or even longer on some systems, with no option to limit the
amount of reported boot lines.
