I use multiple jails (max 3 per host) and never had any problems with that. I use ezjail, so jails are started/stopped by rc.d script. You may wait for more technical answer for that, though. > 3) i would like to build some ports in my jailed process, but for my > environment, this requires mounting the export from my main box on my network. > so far, i am not able to mount a NFS share to /usr/ports (mount_nfs: /usr/ports: > Operation not permitted). I'm not really experienced with NFS but how about mounting NFS share in /usr/ports on host system and then using mount_nullfs to mount that into jails? Just like ezjail uses mount_nullfs to mount host's /usr/ports into jails.
