# HISTORY :
# Description :
# This script can be added to the kernel-img.conf postinst_hook
# variable to be executed on kernel image installs, and add that
# kernel image into the grub menu
#
# A simple script like:
# perl -nle 'print unless /^#Autogenerated by kernel-image $version/
# .. /^#End kernel-image '$version/'
# or for awk fans
# awk 'BEGIN{printit=1}
# /^#Autogenerated by kernel-image $version/{printit=0}
# /^#End kernel-image '$version/{printit=1}
# {if (printit) {print}}'.
# or
# awk '{p=0}/^#Autogenerated by kernel-image $version$/,/^#End kernel-image '$version$/{p=1}{if(!p) print}' < foo
# can be added to the postrm script to remove the lines added
#
# A full featured script is provided in kernel_grub_rm.sh
# a quick hack to add a line to /boot/grub/menu.lst
CONFIG_FILE=/etc/kernel_grub.conf

# The partition where the kernel image resides (in grub syntax)
grub_kernel_partition='(hd0,0)'

# Set this to 'YES' if /boot and / are on different partitions

# Any options come here (especially do not forget root=<root-device> if
# $kernel_not_on_root_partition is set to 'YES'
