I left these questions by Ron to be answered
collectively by fellow Plan 9 folks who would
try out his new "package system".
But the conversation deteriorated into a
"portage: pros and cons" debate/seminar.

My input follows.

I've already created mine. :)

Is `rbind' a recursive bind, that takes care of binding at
all depths? Because that's what you'd need in order
for the binds to work. And then you shouldn't have any
problems.

Really, the installed paths would just be there as a log
of where things went. A straight `dircp' might seem harsh
to some, but in my personal setup, I see no problems with
such a log and my WORM dumps being taken every day.
Then, reverting just means using the history(1) type tools
with respect to the log at /installed/$i. That's only a little
slower than a bunch of unmount(1) commands, but in
totality, keeps a very efficient maintenance system with
no hassles.

If I can come up with a general set of commands to revert
a given package =E0 la history(1)/yesterday(1), I would put
a set of those commands in /installed/$i when the package
is installed. Then you just pass it to rc and you're golden.


Best,
