[gentoo-dev] kernel recompile on existing gentoo system?

[Phil Hall]

Hello, forgive me if I'm being stupid, but is there a way to recompile the
kernel on an up and running gentoo linux system without basically redoing
the entire install? If so I missed it (like I said, I could be just stupid.)
;)

Thanks,
Phil Hall

Of course there is such a way. First download the new kernel sources (either 
by hand or using emerge (emerge gentoo-sources). Then go to /usr/src/linux
Type make menuconfig, configure the kernel, make dep, make bzImage, make 
modules, make modules_install, and cp the new kernel to the boot dir.

Also take a look at man grub to see how you can enable the option to choose 
between kernels.

ps. Of course a reboot is nescesarry to load the new kernel
