Agreed. Having a simple one-shot boot facility would be awesome. If anyone
has ideas on how to accomplish this, please let me know. I'd be willing to
look at implementing this.
Add a byte to the grub config block (wherever setdefault gets written)
indicating whether a boot was clean or not. Have grub set clear that at
kernel load, and then have a userspace app that sets it at the
completion of boot. Check whether it's set or not on next boot and use
that to run a different config stanza.
In theory I think you could do something with the BIOS simple boot flag,
but that could get confusing in a dual boot scenario.
