I don't have a lot of experience with GHC, but I have talked to some
GHC and Cabal developers about how they work with the package system.
Those discussions did not lead me to believe that they have an
especially smooth system for working with packages and updates in-place
--- and, in particular, that it's not the way they normally work. I'd
be happy to hear more from someone who routinely works that way with

I'm not sure what you're getting at here. We seem to agree that the
usual `make` plus `make install` is like Racket's `make unix-style`,
neither of which updates packages (other than the ones the makefile

Ah, no. I've helped Matthias when problems break his installation, I've
noticed that he installs packages not in "main-distribution" (e.g.,
"marketplace"), and I believe he really does want those updated.
I had that context in mind but didn't think to spell it out as I should

You can give each installation a different name (using `raco pkg config
--set name ...`) to avoid the collision. That would be an extra step in
setting up each new installation, though.
I don't have a strong opinion on whether `make` should update packages
outside of "main-distribution", but the feedback I'm getting is
* Sam doesn't think they should be updated --- but he also doesn't
want packages in "main-distribution" updated, so he's going to use
* Everyone else who has spoken up seems to prefer an updating `make`,
