Even though the distro default is /usr/src/linux == currently running
kernel, that rule is so frequently violated I adocate simply requiring a
pointer to the kernel headers. Even if you are currently running the
kernel whose sources are in /usr/src/linux, that might not be the best
version choice for the module being built.

Seems sane to me, with the statement of preference above :) Does the
recently-updated filesystem standard have anything to say on the
subject?
FWIW, the coming-very-soon Linux-Mandrake 7.1 beta will include a system
service "kheader", which is run at boot time to make sure that the
kernel source/include symlinks are correct for the kernel version
currently running.
