Yes, just RELEASE here. On i386 and amd64.

I may have misunderstood how tinderbox does things. I'm intending to build
sets of packages for some twenty or thirty hosts/jails on other machines.
I assume, now, from your comment that I don't use one jail per target
host (just one per arch/os version combination).

Right. I do something very similar with 'ezjail'.
