* prepare image (partimage - my choice, fsarchiver, ntfsclone, dd or whatever works for you), put on disk with the rest of the iles (sample: /image/diskc.000).
* put file named "autorun" in root dir
* if partition: the "rename NTLDR/BOOTMGR, put GRLDR in it's place" installation of GRUB4DOS is the simplest and survives various "repair boot sector" procedures
* if partition: hide the recovery partition, make GRUB4DOS only show additional menu if Esc key pressed (hiddenmenu command)

* if DVD: make image of recovery partition (with image of system partition) rather than system partition,
* if DVD: adjust default kernel loading timeout in isolinux,
* if DVD: an option to re-write mbr makes sense in case the HDD was replaced
System Rescue CD always mounts it's media on /mnt/cdrom (unless you choose to load to RAM)
The disclaimer is going to be different in case of DVD recovery, obviously.
