Initially, I only had the system paths below those. I added these
so that people could have hardware accel by only installing the required
drivers in their local profiles (as recommended in 69971, unless I
entirely misunderstood)

I'm afraid I don't really know what adding stuff to GUIX_LOCPATH would
do. That's for foreign distros, correct? To reiterate, The locale
problem here is that the bubblewrapped process doesn't have access to
the locales, without which it throws warnings.

Hmm, since it's in an ro-bind-try, that'll cause the drivers not to
work, and fall back to trying the system drivers. Is there a better
solution you could recommend?
