I'm with you so far. But if all of Org lives in /path/to/org.git/lisp,
what's to go wrong if it's there vs. /system/path/site-lisp?

Sorry, I never do make install, so that was an oversight.

I'm not sure I follow this one. Does `make up2` look for changed paths
(contrib/lisp vs lisp/) since the last `make up2` ? If not, how would
I know to do `make clean-install` vs. just `make install`?

I'm talking about your original comment that running out of a git repo
can lead to:
- it being just to easy to mess up with the autoloads
- have stale byte-compiled files I forgot about somewhere


John

P.S. And yes, I derailed from the mixed install case due to your
comment as I thought it was worth looking into. I'm doing what you
advise against and I wanted to know the risks and more details about
what I might run into.
