That's exactly what I was thinking of for the Beowulf node problem. For instance: http://www.knoppix.net/forum/viewtopic.php?t=27192 > Beyond using kexec as described above, grub directly supports this; lilo > did too. I know how to do this by changing the configurations, but not how to specify a one time change that doesn't need to be manually undone later. Is either of these boot loaders capable of doing the logical equivalent of: grub-next-boot-only -default 3 (Override whatever default is in the config file, but just for the next boot.)
