For reference, why are these two needed here?  Can't we do this with
the locales and drivers referenced below?  Should we perhaps expand
GUIX_LOCPATH here?

Note that any item you add here which references the user home will
fail to be loaded correctly when using `guix shell' in a way that hides
it; or even just using `guix shell' normally with a user who doesn't
have the hardware-accelerated drivers in their home.  For system paths,
this is somewhat different, since we can more or less expect them to
exist and mirror the layout of other distros to some extent.

Cheers
