[bug#49456] [PATCH] gnu: add environment-modules

[Ludovic Courtès]

Hello,

Nice!  Overall LGTM, modulo cosmetic issues described below.

How about ‘package-management.scm’ instead?

You probably need to add a copyright line for you too.

Should the package name be “modules”, since that’s the name that
upstream seems to be using?

Nitpick: please capitalize sentences and end with a period.

You can omit the trailing #t (here and elsewhere).

Is this change made for tests?  In the build environment, the build user
is potentially in the “kvm” group if it exists, but indeed, /etc/group
lacks “kvm” (see nix/libstore/build.cc:1777).

Should a post-check phase reinstate ‘-n’?

Consider moving the parents on the previous line, as ‘guix lint’
suggests.  :-)

Please write full sentences for the description.

Could you send an updated patch?

Bonus points if you can provide a commit log that follows our
conventions.  :-)
