Rather than editing /boot/grub/grub.cfg directly you need to edit or
replace the files in /etc/grub.d and then call update-grub.
The scripts in /etc/grub.d are executed in order, hence the filenames
beginning with numbers, so if you want to add custom entries at the
top call your file 08_localstuff or something. I've blogged about this
in relation to realtime kernels [1]. Perhaps you can modify that to
suit your needs.


If you just want to include some static text in grub.cfg you could
create a file like this (and make it executable):

#!/bin/sh

echo << EOF

your stuff for grub.cfg goes here

EOF


Hope this is at least a little helpful ⢁)
