LXC: unpriviledged container issue with resoved and /dev/console

Hi

Trying to run an unpriviledged arch guest on an arch host I am experiencing problems with /dev/console and systemd-resolved/networkd. Both ma ybe related. In short, /dev/console is not accessible and systemd-resolved fails to start.
Using classical /etc/resolv.conf does the job, but I would like to have the guest running in a non hackish way. Especially, since the console thingy seems to be an issue with debian and apline guests as well, so I am likely to have a host side configuration issue here.

For the stdout issue, that seems to be the cause for the resolved failure (see journal later on), I figured, that the stdout link points into the void. Persistently after each start of the container. Config issue? Bug?

Any idea what rights may be missing - and how to assign them?

Thanks
