jls usage

I've tried using the actual jail name, and the hostname to be sure - 
nothing - and on checking (jls -v) I'm somehow ending up with the Name 
being the same as the ID. I just put this down to a quirk/bug (it's 
there in 8.2-9) but it sounds like it's not an issue for anyone else. 
I'm defining them in rc.conf:
>>> jail_enable="yes"
>>> jail_list="one two three"
>>> jail_agnet_rootdir="/usr/jail/one"
>>> jail_agnet_hostname="one.mydomain.com"
>>> jail_agnet_ip=""
>>> jail_agnet_devfs_enable="yes"
>>> jail_agnet_devfs_ruleset="devfsrules_jail"
>> You've configured "one" and "two" and "three" in your jail_list, but

>> You have not defined "jail_one_*" or "jail_two_*" or "jail_three_*".

A further clarification - I know using the jail utility defaults the 
jail name to that of its ID if you don't specify one, and presume this 
is the mechanism messing it up here. However as I've gone to the trouble 
of configuring them in rc.conf with names, listing said names in 
jail_list and when commands like:

     service jail start one
     service jail stop one

work just fine, I don't see what I'm doing wrong! Incidentally, it 
doesn't matter if I start them at boot time or start/stop later - the 
jail name always sets to the jail-iD, and not the name specified. I 
suspect a bug in the rc.d script, but I can't be the first person to 
notice, can I??? I'll take a look.
