Well the netbsd bootloader (the one that counts down from 5)
could read a command from a file when the timeout expires.
After all it knows how to access the root directory.
But if you need the mbr_bootsel to do anything you would
have to modify the boot sector - and trust there is space
in mbr_bootsel to fit in the code to unset it (by writing
a copy of itself back).
