Thanks for the help! I have another question now.

> =E2=80=9C(use-package-modules xfce)=E2=80=9D is same as =E2=80=9C(use-m=

What's the difference between a package being downloaded into /gnu
instead of the system profile, and when should I use the package module
instead of installing it normally? To me it seems like the only reason
for using a package module is for easier deployment, is that right?

Thanks,
Keith
