We do, but the new way I'll be packaging the source doesn't require any kernel
source in debian. Whatever xen ships, will be in the xen deb.
I'd prefer to only use real releases; if I have multiple xen versions, then it
becomples complex with file overlaps and dependencies and parallel installs.
And, even then, it's not hard to see a point in the future where a new linux
kernel comes out, but xen-stable(3.0) doesn't upgrade to it, and then the
source I do require gets removed. My new way gets rid of all of these
problems, and makes the local admin get the kernel source his own way.

In vif-common.sh, ip_of should be this:
==
function ip_of()
{
ip addr show "$1" | awk "/^.*inet.*$1\$/{print \$2}" | sed 's,/.*,,'
}
==
Sorry it's not in diff form, I just pasted what is on our production server.

Well, not delete. Maybe dump to a text form, then reimport.

That's true, but the xen hypervisor is not compiled by users; it's built once,
and installed thru a deb.

Then that sounds like a candidate for xen-debug.deb.
