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.... :-) > One more sequence: > > make buildworld > make installworld > update some sources > make buildworld > > For that the installworld may be the larger > change compared to the source updates as far > as contributions to rebuild activity go. > > This sort of thing is likely what you had > happen. > .... Hmm.... Thanks again. Peace, david -- David H. Wolfskill david@catwhisker.org Do these ends really justify those means? See https://www.catwhisker.org/~david/publickey.gpg for my public key.
