Well, what I actually meant is that if you automate something like "make
modules_install" to run unattended it makes sense to put in some checks.

Such an automated build should never overwrite your modules and it
should be fairly easy to protect your system from doing that. For example
make the appropriate places writable for a dedicated kernel build user
in advance, do the kernel build/install as that non-root user and
revoke the rights afterwards.

Also, it is fairly easy to _set_ the extraversion by a patch script and
to undo it again after the kernel build (so the next ac level will patch
cleanly). If you know the name of the patch you know the EXTRAVERSION.

Don't build kernels as root. Give the [dedicated] user (e.g. "src",
"linux", "boot") enough power to do just that job or do the last step
manually as root (that's what I do).
