Details:

>From version 2 forward maintain backward compatibility with a limited number
of file system modules and an autorecovery module. This module would work
together with a wrapper around grub-install.

The feature in the module would work as follows:
When an error is encountered but before dropping to grub recovery the system
will look for and try to load the autorecovery module.

It will alert the user and ask if it should try to recover or drop to the
prompt. If the user chooses to recover the autorecovery module will search for
a folder containing a file called grubbuild that contains the build id of the
stage 1 binary. It will then try to set prefix and insmod and execute normal.


The wrapper or addtion to grub-install would look in the place that grub will
look for modules and will check to see that the grubbuild matches the stage 1
binary. If it finds a mismatch it will offer to backup and update this
directory with new modules. 
It would also ask if you want to retain older versions in a backup folder or
discard them.
