Re: Building kernel modules for stock kernels is a hell of a job!

	Unfortunately, several people disagree with that conclusion.

	There are two constituencies here. One set wants to just have
 the minimal install, and another wants both headers and the kernel
 image. The obvious solution is to give people a choice, which is what
 we do now. 

	The headers and sources are provided by debian in precisely
 the same place that the kernel images are.Any one who chooses to have
 headers installed can get them from the same place they got the
 image, and all the package management tools are there to help them do

	I am not a proponent of reducing choices (and chosing not to
 have kernel headers installed is a choice) for the sake of dumbing
 down Debian so we get rank novices who probably have no business
 compiling modules in the first place -- if you cant figure out which
 kernel image goes with which header from the above list, yes, I do
 mean you.
