libGL diversions

[Andreas Beckmann]

Hi KiBi,

now that I have to redo the diversion handling :-), I'd like to do it a
bit more general, so that fglrx can use it, too. What would be a good
destination for the diverted files?
* /usr/lib/mesa - but you might need this for other things
* /usr/lib/mesa-diverted
* ...
(I don't want it to include the names 'nvidia', 'fglrx' or 'non-free')

Furthermore I want to introduce a global alternative 'glx' where the
user can run
    update-alternatives --config glx
and gets the choices
- /usr/lib/mesa (or whereever the diverted files live)
- /usr/lib/nvidia
- /usr/lib/fglrx (or something like this)
and a set of slave alternatives is being setup so that all libraries
(libGL.so.1, but *not* libGL.so, libglx.so Xorg module etc.) are
switched at the same time avoiding "mixed configurations".

Any objections to the alternative named 'glx'?

About diverting multiarch libraries ... as I need to divert
libGL.so.1:amd64 and libGL.so.1:i386 at the same time to avoid weird
behaviour, I want to use a MultiArch: foreign diverter package that is
aware of the two triplets {i386,x86_64}-linux-gnu. Where should I put
the diverted files? /usr/lib/<triplet>/<diverted> or better
/usr/lib/<diverted>/<triplet> as /usr/lib/<triplet> may not exist and I
don't want to create it?

PS: now I can also start to switch Nvidia to multiarch - thanks!

PPS: forward this message to mesa etc. discussion lists as you see it fit
