I was looking for advice for adding a pre-existing jail to Warden.
EDIT: Took the plunge and just did an import. Data still there in the /portjail. Import via ncurses warden using jls info went well
jls in Terminal yields
foob@pcbsd6151 /usr/home/foob]$ jls
JID IP Address Hostname Path
1 192.168.1.59 pcbsd-6151 /usr/jails/portjail
It was possible to proceed via warden menu to add the IP of 192.168.1.59 and hostname of pcbsd-6151, tick neither system source nor ports tree (as I already have a valid ports tree) but tick "on" Start jail at system bootup
##first time I've seen a registered symbol in a url
and viewed previous on warden in 9.0 handbook viewed handbook of Freebsd 9.0 and forums.
The article in the BSD May 2012 magazine on warden was helpful also
Impressive that Calibre went to 8.50 without a glitch via portsjail console. Now just to finish off the steps to get X to work from jail.
