mount_unionfs for jails

[David Polak]

Using freebsd 7.0-release, I am trying to use unionfs to simplify my jail
setup.

Here is what I am trying to do:

mount_unionfs -o below /usr/jails/basejail /usr/jail/jail1

after I do that I edit /usr/jail/jail1/etc/rc.conf and add the appropriate
entries to the host system rc.conf, but when I start the jail it starts
using the settings from /usr/jails/basejail.

Is my mount_unionfs syntax wrong, is this a bug in unionfs (man page says
unionfs is broken, but doesn't specify how its broken) or is this expected
behavior?
