Hi Surreal,
You can do changes to the final binary by putting a hook in
config/binary_local-hooks/. Those hooks will be executed after the binary is
built, but before the final binary image is created (iso or img file).
I use syslinux/extlinux, not grub, so the following have to be adapted to
grub and to your case.
#!/bin/sh
echo "BINARY HOOK: syslinux changes."
# check if menu was already changed
CHANGED=`grep -i '#EDITED' *`
if [ -n "$CHANGED" ]; then
# It was. Skip further changes."
echo "Menu was already edited, skip it."
exit 0
fi
LIVECFG=`find binary -type f -name live.cfg`
# lenny syslinux is different from the latest one.
# The menu file has a different name (menu.cfg/live.cfg).
if [ -n "${LIVECFG}" ]; then
echo "Found live.cfg."
else
echo "live.cfg not found, searching for menu.cfg."
LIVECFG=`find binary -type f -name menu.cfg`
fi
echo $LIVECFG
# mark the menu as edited/changed so its not edited again.
echo "#EDITED" >> ${LIVECFG}
# get the first option as template file
head -n 5 ${LIVECFG} > menu_template
# add some boot options to syslinux (reverse)
# A - encrypted home
# B - persistent
# C - integrity-check
# C - integrity-check, verifies against md5sum.txt
cp menu_template menu_check
sed -i 's/label live/label livecheck/' menu_check
sed -i 's/Start Debian Live/Integrity Check/' menu_check
sed -i 's/union=aufs/union=aufs integrity-check/' menu_check
# copy the new menu after the default first one
sed '5r menu_check' < ${LIVECFG} > new_menu
mv new_menu ${LIVECFG}
# B - persistent
cp menu_template menu_persist
sed -i 's/label live/label livepersistent/' menu_persist
sed -i 's/Start Debian Live/Start Debian Live Persistent/' menu_persist
sed -i 's/username=live hostname=cruzador/username=my_name
hostname=my_hostname/' menu_persist
sed -i 's/union=aufs/union=aufs persistent=nofiles/' menu_persist
# copy the new menu after the default first one
sed '5r menu_persist' < ${LIVECFG} > new_menu
mv new_menu ${LIVECFG}
# A - encrypted home
cp menu_template menu_lukshome
sed -i 's/label live/label livelukshome/' menu_lukshome
sed -i 's/Start Debian Live/Start Debian Live LUKS home/' menu_lukshome
sed -i 's/username=live hostname=cruzador/username=my_name
hostname=my_hostname/' menu_lukshome
sed -i 's/union=aufs/union=aufs lukshome/' menu_lukshome
# copy the new menu after the default first one
sed '5r menu_lukshome' < ${LIVECFG} > new_menu
mv new_menu ${LIVECFG}
# delete template files
rm menu_check
rm menu_persist
rm menu_lukshome
rm menu_template
# create extlinux.conf
SYSLINUXCFG=`find binary -type f -name syslinux.cfg`
# if not found, search in isolinux
if [ -z $SYSLINUXCFG ]; then
# check for isolinux
SYSLINUXCFG=`find binary -type f -name isolinux.cfg`
fi
# if still empty, no syslinux or isolinux, maybe using grub(?) or extlinux,
so skip it.
if [ -z $SYSLINUXCFG ]; then
echo "No syslinux or isolinux... skipping."
exit 0
fi
# copy to extlinux.conf
SYSPATH="$(dirname ${SYSLINUXCFG})"
/bin/cp ${SYSLINUXCFG} ${SYSPATH}/extlinux.conf
# NOTE: to install extlinux, mount the partition as /mnt and
# run "extlinux --install /mnt/live/syslinux". This will overwrite the
MBR!!!
# If you use grub in the MBR, then re-install it with "update-grub /dev/sdX"
# EOF
Don't forget to make the hook executable.
Have fun.

I installed linux-source-2.6.26 in /usr/src, modified some configurations,
and used make-kpkg command to generate a kernel deb file.
On installing the kernel on my local machine, I found that the kernel was
entered as *title Debian GNU/Linux, kernel 2.6.26 (single-user
mode)*in /boot/grub/menu.lst
I installed this kernel image on my live cd, and then installed it to my
hdd.
Inspite of me making modifications to the kernel, its still showing *title
Debian GNU/Linux, kernel 2.6.26 (single-user mode)* in the grub bootup.
Then I installed the same very linux image deb file in Ubuntu 8.10, and even
there the kernel was listed as that of Ubuntu..!!!
How do I change this title to that of my own?
How to customize the kernel title in /boot/grub/menu.lst automatically
without user interven?
Its a fair thing that if i customize a kernel according to my need, I should
be able to use a name for it too..!!
Any idea of how to do this??
The uname of my live cd and machine is
Linux indiaforce 2.6.26 #1 SMP Thu Oct 1 09:03:37 IST 2009 i686 GNU/Linux
Now how to enable indiaforce ie hostname to appear in kernel name?
Please help.
