Default Bug#497755: linux-image-2.6: Separate desktop and server kernels

Package: linux-image-2.6
Severity: wishlist

The differences between desktop and server requirements are great. The kernel Hz is an excellent example
of this - servers seem to require as few as possible while desktops need as many as they can get their
hands on. The compromise in the Debian kernel is 250, which leans heavily towards the server side. Another
example is kernel preemption - this seems to be a bad thing for servers while more is better for desktops.
Again, the Debian kernel defers to the server(the kernel is completely unpreemptable). By using separate
kernels, the server flavor can be completely optimized(instead of mostly optimized) while desktop users
will get a kernel designed with them in mind(say, 1000Hz and totally preemptable, including the RCUs
once that feature matures a bit; maybe use the ondemand governor
by default) without needing a recompile
(Debian != Gentoo).
