Component

Expected behaviour you didn't see

You should be able to see nspawn containers from the host like this link:

/var/log/journal/b09525e2811f46958ba6adea13140842: symbolic link to /var/lib/machines/mail/var/log/journal/b09525e2811f46958ba6adea13140842

Unexpected behaviour you saw

Instead the symbolic link is broken:

/var/log/journal/b09525e2811f46958ba6adea13140842: broken symbolic link to /tmp/nspawn-root-96f233//var/lib/machines/mail/var/log/journal/b09525e2811f46958ba6adea13140842

Additionally, /tmp/nspawn-root-96f233 is entirely empty.

Steps to reproduce the problem

Upgrade to v258 and run a container like this:

systemd-nspawn --quiet --keep-unit --boot --link-journal=try-guest --network-veth -U --settings=override --machine=mail

Possibly caused by 88252ca8893 ?
