Excellent!

This looks like it would not work with profiles installed anywhere else.
I’m not a fan of hard-coding ~/.guix-profile, because I know that many
people here at the institute use per-project profiles at custom
location. Any mechanism that relies on things to be installed to
~/.guix-profile will fail them.
Could this be made profile-agnostic? Perhaps the GUIX_PROFILE
environment variable could be referenced?
Thanks for working on it!
