You can just put them all on the same line, i.e.,
make-kpkg --append-to-version -2.635amd64_custom kernel_image
kernel_headers kernel_source
I don't use the -j3 switch, and I don't think that -j3 switch works
like you think it does when using make-kpkg, at least, not if that's
meant to utilize multiple processors when building. I'm at work right
so this is all from memory, but I think the correct way to do it is to
do
export CONCURRENCY_LEVEL=3
where the number you provide is 1 + the number of processors you have.
So if you have a duo-core, it's 3. If a single processor it would be
two. And so forth. I seem to recall something in the make-kpkg
documentation saying not to use the -j switch.
Hopefully someone will correct me or provide more authoritative
sources than this sorry excuse for a memory I have.
As for your sources bug being symlinked incorrectly, I think I can
confirm, however it hasn't negatively affected anything. Things still
build properly against the headers / sources on custom kernels even
when the build directory in my home dir is removed. But yes, I'm
pretty sure I've seen warnings about it not being able to find sources
in /home/arthur/linux/kernel/2.6.35/, though they are just strange
warnings and I haven't bothered looking into it further since
everything seems to still work fine.
Best,
