Pct restore lxc container with PBS

Hi,

Is it possible to use pct restore to restore a LXC container when a backup is made in PBS?
pct help restore doesn't seem to have any arguments to support that.

I'd like to convert privileged containers to unprivileged, but for that I need to add the flag "-ignore-unpack-errors 1".
Otherwise it results in the error "Error: error extracting archive - error at entry "random": failed to create device node: Operation not permitted (os error 1)".

Thank you!
