[cgl_discussion] configurable requirements - are they specified

Thanks for coming by and providing your thoughts on
this matter. I thought I'd share a summary with the rest of the
discussion list in order to close this matter.
In summary, it would be impractical to perform tests with some
requirements configured in and some out. I agreed with this and
I wasn't trying to change that. My point was that we have seen
build failures in the past where someone tried to configure out a
requirement by changing the config file. I wanted to suggest that
we could run a series of compile tests to assure that this problem
would not occur. Your point was that this was redundant work because
the distributions would configure the kernel a certain way and they
would be able to test this for us.
Another point you made was that if configurations were tested, then
where do you draw the line. Its a lot like the story of an acclaimed
children's book: If You Give a Mouse a Cookie.
Both these points are well made. I guess we can let the distros play
with various configurations and let them figure out what the name/value
pairs need to be to get a requirement configured in our out.
