Thanks for that information, that was what I wanted to know (both the where
does it come from, and the how to avoid it being pulled in)
I think a "guix revdep $PKG" should be a valuable tool
it should work:
1 - globally in the list of defined packages
2 - locally in the list of packages from the current user's profile
3 - systemly, from the list of installed packages in the system profile
I'm trying Eric's suggestion (thanks Eric), and that seems to do 1, I need
a way to modify it to do the other 2... (see the attached script)
WDYT ?
