I haven't used it, but GHC has an in-place build option where you can install packages; see [1]. From their wiki, it looks like `git pull && make` will update both the compiler and the "boot libraries" (the ones used by the compiler), plus any that you've listed as "extra" explicitly [2], but not any other packages. However, it doesn't seem like they expect people to use this as the "standard" way to build the compiler the way we do for Racket. [1] https://ghc.haskell.org/trac/ghc/wiki/Debugging/InstallingPackagesInplace [2] https://ghc.haskell.org/trac/ghc/wiki/Commentary/Libraries I think the closer analogy is to what other software does when you run both `make` and `make install` analagous to Racket's unix-style installation, since that's the recommended way of building (eg Python), just as in-place is the recommended way of building Racket from source. I don't think any of those systems update packages when running `make install`. > At Tue, 17 Feb 2015 17:40:36 -0500, Matthias Felleisen wrote: >> Speaking as the user I am, I really like it that make updates >> my extra-pkgs. > > Package scope provides one a way to get these different behaviors.

I expect that the packages that update for Matthias on `make` are packages in "main-distribution", and thus just switching to `raco pkg update --update-deps main-distribution` would still make him happy (and be more like the old `git pull && make`). As an aside, the reason I don't install in user scope is that I switch between Racket implementations regularly, which would lead to out-of-date zo errors for all my user packages (instead, I get multiple copies of the packages). > Another possibility is that the packages installed by `make` should go > into a scope that's even deeper than installation scope.

Whether that changes Matthias' work flow depends on what packages he's relying on `make` updating, right?
