Somewhat. My /usr/obj/ today is local to the buildworld's sysdisk so no
NFS is involved in writing to /usr/obj/ -- only /usr/src/ is from NFS,
and it is read-only.

But some of the notes in the bug make me wonder if moving /usr/obj/ to
NFS, as well as /usr/src/, might somehow produce different results.

The NFS /usr/obj/ export would have to be writeable, of course, but I'd
prefer to keep /usr/src/ read-only, assuming that's a supported setup
for buildworld.

That aside, I still wonder about buildworld having some problem with
"/usr/src/" vs. a /usr/src symlink which points to "/net/srv/...".

Thanks,
