I am considering upgrading my kernel from 2.4.21 to 2.6.0-test1.No. Just the kernel, and ALSA / pcmcia-cs if you use them.
When I do this will I need to recompile my entire system?
What about recompiling glibc against the new kernel? Will I need to do that?Again, no. All you should have to do:
* emerge sys-kernel/development-sources
* copy your .config from /usr/src/linux-2.4.*/ to /usr/src/linux-2.6.*
* update the /usr/src/linux symlink
* make menuconfig, and check everything carefully. There's a lot of new stuff. In particular, make sure you enable the relevant keyboard and mouse support. It's now possible to disable AT/PS2 keyboards and mice (oops...).
* compile
* do whatever's necessary with ALSA / pcmcia-cs if you use them
* mount /boot and copy your new kernel. Best to give it a different name (eg bzImage.2.6.0)
* do whatever's necessary to your bootloader (lilo / grub)
* reboot
