Failed unmounting /var on shutdown

Hi all,

looking at the journal, I get this towards the end of every shutdown:

Apr 30 22:25:00 host.home systemd[1]: Failed unmounting /var.

.

These are more messages of things that don’t look right, before that (in reverse order):

Should I be worried about it?

Hi
AFAIK it’s because it’s still writing info to the journal, it gets shutdown cleanly later on by systemd.

I see an old thread here (Leap 42.3);

ok thanks! I did find that, but there seems to be no definitive answer… anyway I guess I shouldn’t worry about it then.
