[ILUG] Kernel install script

[Kenn Humborg]

Here's something I just knocked up for myself.  Other Red Hat
users might find it useful.

Later,

# Standard disclaimers apply.  If this breaks your

# This script should be run as root from the root dir of a linux
# kernel source tree.  It does the following:
#
#  o  does a make bzImage modules
#  o  determines the full kernel version from include/linux/version.h
#  o  copies arch/i386/boot/bzImage to /boot/vmlinuz-<VER>
#  o  copies System.map to /boot/System.map-<VER>
#  o  copies .config to config-<VER>
#  o  installs the modules after cleaning out old modules
#  o  if a reference to this image exists in /etc/lilo.conf, it 
#     runs lilo, otherwise it prints a warning that lilo.conf 
#     needs to be edited.
#
# To get the full benefit from this script, you should change
# EXTRAVERSION in the kernel Makefile whenever you want to try
# out a new kernel config.  E.g. I usually use -kh1, -kh2, etc.
# This way multiple kernels (and their modules) can live side-by-side
# and can be selected via LILO options.  The Red Hat boot scripts
# will find the right modules and link /boot/System.map to the
# correct System.map for you.

# First look for the files we expect to find in a kernel source root
