Hi,
I am facing a peculiar issue where a system reboot sometimes & not always
posts a crash in last output.
root pts/0 Wed Dec 4 11:47 still logged in
reboot system boot Wed Dec 4 11:30 - 11:57 (00:26)
root pts/0 Tue Dec 3 18:14 - crash (17:16)
reboot system boot Tue Dec 3 10:03 - 11:57 (1+01:53)
root pts/0 Mon Dec 2 18:03 - down (15:56)
reboot system boot Mon Dec 2 11:19 - 10:00 (22:40)
root pts/0 Sat Nov 30 17:22 - crash (1+17:57)
reboot system boot Sat Nov 30 10:36 - 10:00 (2+23:24)
root pts/0 Fri Nov 29 17:35 - down (16:56
I then created an alias - alias reboot='sync && sleep 3s && sync
&& sleep
3s && /usr/bin/systemctl reboot'

journal entries do not show any errors, but it is recorded as crash in
last since there's no entry of - shutdown system down - in last.
last records sometimes a proper shutdown, many times as crash even though
the reboot is done similarly all the times.
What could be the issue or should I be concerned about it.
