Sounds reasonable to me. One thing I'd like to see in 3rd
party vendor's driver installers, is to have them install
'replacement' modules (ie: libglx.*) in a separate and
nonconflicting location that does not overwrite OS supplied
That's something that has been a troubling support problem for a
while now, which I think would be useful for everyone to work
together on a common solution of some sort, as this support
problem impacts end users and distribution vendors negatively,
and I have to assume that it also causes support problems for
the driver vendor also.
Currently this can be done with ModulePath directives in the
config file listing the vendor's module path first, and then
falling back to the X.Org module path, etc. It would be
much nicer to somehow have this all happen automatic and not
require configuration though.
Any thoughts as to how we might best proceed with such a
