On slow servers / storage drives this execution can easily take 10 seconds
or longer. But there is an alternative that is quite fast and even shows
the booted kernel version:
# last reboot -F -n10
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, as simulated and visible above, a duplicated "until" field
hints that the earlier system boot (16:25:41) crashed unexpectedly (sometime
before the next boot at 16:29:17).
Limiting the output to 10 lines seems reasonable for most cases.
