No cause Linus has already told that /usr/src is for the
kernel source that your system was compiled with. I always
put my kernel source in opt.

I never use this since my source is in opt.

It is not twice. 'make oldconfig' updates the .config file
with new options that are in the new kernel. Besides, the
proper way to do it is to run make oldconfig.

'make c;ean' _should_ always be run. You do not know
what state the kernel source is in. This cleans it up
and leaves it in a state suitable for your system.

Bad idea. See above.

I notice ppl love seeing all the stuff scroll across their screen.
I never saw the point of it. tar xjf linux-xxx.tar.bz2 is good enuf
for me. Your cp command is wrong. It should be cp /boot/config-xxx \
.config .

Try this instead:

make oldconfig xconfig dep clean bzImage modules
su -c "make modules_install"
su -c "make install"

Not how the command is strung out on one line. If
any step fails, the build process stops. With your
method, the next step is attempted and will most
likely fail at the same point repeatedly. My method
works for those of us who build kernels as an ordinary
user and not as root.

All of this is taken care of by 'make install'.
