stupid question: building packages for different archs

[Fernan Aguero]

Hi!

maybe this is obvious or too stupid.

Is it possible to build packages for different architectures
(i386, amd64) from a single tinderbox installation?

I have some new hardware that I'm setting up, and I'm
planning to keep a local copy of the FreeBSD CVS tree, and
share via NFS the src, doc, ports collections from a central
server, essentially as described here
http://segment7.net/projects/FreeBSD/dev_setup.txt

Now, I'd also like to build packages for all my workstations
and servers using a tinderbox on this main server. Right now
this would mean building packages for i386 and amd64.

Is this possible? When the README mentions creating 'jails' and
build environments, it only talks about different _branches_
of the src collection paired with a checkout of the ports
tree ... but there is no mention of archs.

pointyhat is building packages for different arches ... is
the build farm a single-arch farm? Or is it a multiple arch
farm running several independent build environments?

Thanks, and sorry if my questions are too dumb ... I'm sure
they're perfect for a tinderbox FAQ :)
