Does anyone know of a way of hiding mount point information for
file systems that lie outside of a chrooted jail environment?

    sosai% mount
    /dev/ad0s1a on / (ufs, local)
    devfs on /dev (devfs, local)
    /dev/ad0s1g on /data (ufs, local, soft-updates)
    /dev/ad0s1f on /tmp (ufs, local, soft-updates)
    /dev/ad0s1e on /usr (ufs, local, soft-updates)
    /dev/ad0s1d on /var (ufs, local, soft-updates)
    procfs on /data/jails/brightstorm/proc (procfs, local)
    devfs on /data/jails/brightstorm/dev (devfs, local)
    procfs on /proc (procfs, local)
    procfs on /data/jails/obleo/proc (procfs, local)
    devfs on /data/jails/obleo/dev (devfs, local)
    sosai% ls /data
    ls: /data: No such file or directory

The entire jail is rooted off /data/jails/brightstorm/.  I'm not
sure what I would like to see from mount, but it is a bit unnerving
to have information that is only relevent to the host environment
appearing in the jail.
