    freebsd-update(8): Add -j flag to support jails
    
    Make freebsd-update(8) support jails by adding the -j flag which takes
    a jail jid or name as an argument. This takes advantage of the recently
    added -j support to freebsd-version(8) in order to get the version of
    the installed userland.
