My /sbin/installkernel

This is my slightly modified /sbin/installkernel script (it get's called if i do a make install for a new linuxkernel).
I install my kernels in /kernel (and delete old kernels about twice a year).

#!/bin/sh
# Arguments:
#   $1 - kernel version
#   $2 - kernel image file
#   $3 - kernel map file
#   $4 - default install path (blank if root directory)
#
fdir=$4/kernel/
fname=$1
fcount=0
$liloconf=$4/etc/lilo.conf

mkdir $fdir 2>/dev/null

fthis=$fdir/$fname
while [ -f $fthis ] ; do
        fcount=`expr $fcount + 1`
        fname=$1.$fcount
        fthis=$fdir/$fname
done

echo will install as $fthis

awk -v fname="$fname" -v fthis="$fthis" '
BEGIN { found=0 }
/^image.*=/ & found==0 {
        print "image = " fthis
        print "    label = " fname
        print "    root = /dev/sda3"
        print "    vga = NORMAL"
