Hi all, hi Clement,

I updated the rcng jail start script to mount devfs and procfs
into the jail if wanted. Adding entries to /etc/fstab didn't
work properly, because the jail filesystem wasn't mounted when
the startup process wants to mount it.

Going this way allows us to control which jail could be used
via ssh (or another remote shell), too.

Any comments gladly welcome.

If it's useful for FreeBSD, I will write the rc.conf(5) update,
too. Please inform me to do this.

Regards,
Jens
