Public bug reported:
Binary package hint: grub
(I don't know if this is grub or grub-installer)
It would be nice if grub-install could default to always setup the boot
sector of the / or /boot partition to be chainloadable also (as a
backup).
* Recovering from an overwritten MBR would be as easy as chainloading
the /boot or dedicated grub partition. (With a DOS mbr in place only the
boot flag of the /boot partition needs to be set.)
* update-grub could by default generate simple menu.lst entries (root
<grub partition>; setup (hd0)) to setup or recreate MBRs (hdX) or
floppies (fd0) to boot /boot/grub
* It is very convenient to have a dedicated grub partition to boot
parallel installations of a distribution or different OSes.
* A dedicated /grub partition on hd0 can be created by mounting a
partition from hd0 to /mnt and issuing "grub-install --root-
directory=/mnt (hd0)".
* The dedicated grub partition will just need maintainance free
chainloader menu.lst entries.
* Grub on a read-only boot media (floppy, cd, dvd, usb,...) could check
the integrity of MBRs, grub and /boot partitions.
** Affects: grub (Ubuntu)
