A layered filesystem (such as unionfs) would be useful in this
situation. Something like per-process mounts would be even more useful
(doing a mount visible only to the "make package" process and its
descendants. I guess Hurd could to it. But I digress... )

Yes, that's I was talking about. If you dont'want to install the
package, you just skip the pkg_install phase, and you can do it as
non-root, I guess. Wouldn't this solve the syspkg problem too?
