>Description:
A simple patch adding an rc.conf-variable to make /etc/rc.d/jail run 'zfs jail
$jid' on all
filesystems with 'jailed=on' set beneath the path specified in
jail_$name_delegate_path.
>How-To-Repeat:
>Fix:
Patch attached with submission follows:
# $PIL$
Add a jail_NAME_delegate_path-variable to rc.conf, which'll delegate
all jailed zfs's under that path to the newly-started jail.
