systemd-nspawn containers - error on shutdown

Appears to have started a few weeks ago. Only just noticed it - seems harmless, but it sometimes delays the container shutdown:

[FAILED] Failed unmounting Temporary Directory (/tmp).

I'm suspecting the glibc upgrade (2.27 -> 2.28)

Anyone else can reproduce? Any tips on how to debug?

It's as simple as :

# pacstrap -i -c /path/to/container base --ignore linux
# systemd-nspawn -b -D /path/to/container
# poweroff

Re: systemd-nspawn containers - error on shutdown

I can reproduce it. I have it every time a container shuts down and also with every container.

From within a container:

$ sudo LANG=C umount /tmp
umount: /tmp: target is busy.

$ fuser -cu /tmp
$

$ LANG=C fuser -cu /tmp
$

$ LANG=C lsof /tmp
$

I have no clue...
