First: Thank you for replying & suggesting the above.

That said, one of the machines in question is my local "build machine" --
and for it, in addition to in-place source updates, I also do (weekly)
updates of my "production" machines (at home).

And for that case, the production machines mount the builder's /usr/src
and /usr/obj (via NFS) read-only.  And without complaints of attempts to
scribble on read-only stuff. :-}

So if "make installworld" messes with anything that META_MODE cares
about ... that would appear to be somewhat surprising.

Mind, I've been wrong before, and I do intend to live long enough to be
wrong again.... :-)

Hmm....  Thanks again.
