It will change the symlinking in /biit so that the entries the installer set up will boot to the new kernel. The lilo entries point to the symlinks in /boot, so if you change th esymlinks, the entries boot whatever the symlinks point to.
> Does lilo get updated in such a way to allow booting to old kernel? Not on the first update. Every kernel update adds an explicit choice for itself in the bootloader menu. This allows you to boot into a previously installed kernel if the new one does not work as advertised. The only problem with this is that the first kernel install does not install itself with an explicit entry, only the symlink ones, so if you want to be able to boot the original kernel, you have to add an entry for it to lilo.conf manually. > Or should I attemp a configure and build from the source rpm according to a > HOWTO? Not necessary unless you would like to experience the thrill of building your own kernel, in which case you will want to install the kernel-source package and then follow the various instructions. The kernel SRPM will only build the kernels exactly as you see them on the mirrors. -- /g
