The question is: how should primusrun/optirun work in a GLVND
environment? There is no longer the "vendor" libGL.so.1 that has to be
loaded instead of the system libGL.so.1
As I understand it, GLVND is supposed to provide a better solution to
the underlying problem addressed by primusrun/optirun.

Note: if libgl1-nvidia-glvnd-glx is used (instead of libgl1-nvidia-glx)
and libgl1 (from src:libglvnd) is installed instead of
libgl1-glvnd-nvidia-glx, there is no longer a nvidia-provided
/usr/lib/*/nvidia/libGL.so.1

(Note for Timo: for the nvidia drivers we still need to divert the
system libGL.so.1 (and much more) since the legacy 304xx, 340xx drivers
don't support GLVND and we therefore still need to use the nested
alternatives, and we want to have them co-installable with the current
drivers)

That is intentional to allow the nvidia packages into testing which
still has mesa 13.x and no libglvnd. You should be fine with the libgl1,
... packages from src:libglvnd in sid.
