!! Some notes
-Using
[DistCC] for KernelDevelopment can
be problematic
.
+In theory you can use
[DistCC] or [ccache | http://ccache.samba.org/] to speed up compilation but IanMcDonald hasn't been able to get them to work with the kernel (he would love to be told how to though). The problem seems to
be not so much with those products but the fact that when you do a make with a -j option it gets screwed up (-j does parallelisation)
.
-In theory [ccache | http://ccache.samba.org/] should help speed up compilation as well. I'm testing it and will update -- IanMcDonald

It has also been suggested to me to use kgdb with qemu and/or kgdboe to help with debugging.
