something like this might not be bad anyway.  OpenBSD has implemented
something they call "fake" which when building a binary pkg, installs to a
fake dir (I haven't looked to see if its done via chroot).  Then the PLIST
is used to tar up the result.  They did it to avoid stuff being installed
that wasn't correctly listed in PLIST.  But such a thing might be good, as
you suggest, for upgrades.
