provide emergency path for when entire initscripts are broken

[Joshua]

Binary package hint: grub-common

A couple of times I've taken a bad update that rendered the screen unusable before the recovery prompt comes up.

Really fun to start sshd blind so I can remote in from another computer and fix it.

The only other generally working option is to keep a third boot path from a known-good kernel that touches no bootscripts.

My particular solution was to modify /etc/grub.d/10_linux to generate the third option. As you can see, it only functions if /etc/init.d/emergency-shell exists and is executable. So, to enable, ln -s /bin/sh /etc/init.d/emergency-shell and run update-grub.
