Absolutely correct. /usr/src/linux should contain the headers to the version 
of the kernel your glibc was compiled on, IIRC.

I usually use /usr/local/src/linux. /usr/src/linux shouldn't be used; but if 
you ever want to patch your kernel with something hardcore (FreeS/Wan springs 
to mind) you'll need to do some real work if it isn't there. I discussed this 
with the FreeS/Wan guys about six months ago; they didn't really seem to 
care. Although I can see their side of it too: linux sources are most likely 
to be in /usr/src/linux. MPOV is that if someone's applying a kernel patch 
they ought to bloody well know where the source is located, but there we are.

I wouldn't have thought so, although perhaps the source rpm contains a build 
script to build it in the SuSE common method (i.e, can you build a binary 
with rpm -ba linux.src.rpm, or however rpm does it?)

If in doubt, compile everything as a module (except for filesystems and IDE 
device drivers :). If you're not using it, it won't get loaded: you just pay 
for the extra compile time, which I suspect shouldn't bother you too much.

Cheers,
