Right.

Right.

Um. I'm not sure I follow you on this one. Do you mean that I would have
${BSDSRCDIR}/bin/cat/obj be a symbolic link to an objdir on a writeable
partition?

If you mean this, then you are not describing my situation. I call
build.sh with the "-O objdir" argument. This creates a completely
separate object tree for me. And in that case:

Wrong. I have set "-O objdir", but the cleandir most certainly happened in the
read only source tree. I know this because I accidentally did cvs checkout
without -P, which caused usr.bin/ktrace to have a (empty) subdirectory called
ktrace, so cleandir bombed because it did "rm ktrace" in usr.bin/ktrace.

(Oh, and of course at the cleandir phase the (real) object tree did not even
exist, so...)

Certainly, I can understand this.

However, I had an objdir and I was just wondering why cleandir was not done
there, but in the source directory. Of course, it didn't matter because
there was nothing to clean in the source...
