How should it be handled?

I’m under the impression that ‘va_gl’ is the generic driver that works
for everyone, but that there might be optimized drivers for specific
pieces of hardware, is that correct?

If it is, we could always use ‘va_gl’ as the default.

As for LD_LIBRARY_PATH, perhaps we need a central location for these
drivers on GuixSD, like /run/current-system/vdpau?
