Does this mean that the installed software in the jail is 'fixed'? I.e.
installed software on host == installed software in jail? Or do you only
r-o mount /bin, /sbin, /usr/bin, etc. etc.? I've been considering such
an approach, and have already started making it an option in my script,
however wether or not this is wanted depends highly on how it's
implemented and what use you have for the jails.
Obviously in a jail that is acting as a true 'virtual server', this will
be less than optimal.

Good idea. Where can I find yours? I'm trying to write a manpage for
mine, then I'll pack it up and throw it up on my website. I will
probably put together a port aswell, but I have no idea how to proceed
with that ;)
