I included a link to the "Booting once-only" node of the grub info page in my previous post, and I didn't get that impression from reading it. My interpretation is that grub-set-default-- by itself-- isn't capable of overriding the default boot entry in grub.conf for just one time. Instead, the info page recommends using grub-set-default to set your desired boot entry for the next boot only, and then *also* specifying your "normal" default with a "savedefault" directive in each of your boot stanzas in order to reset it to what you really want to boot from next time. It seems like if you used grub-set-default and omitted the savedefault directive from whatever you were booting, grub would never have its default boot entry reset to its "normal" value. If you used grub-set-default and did nothing else, then you'd always boot the new kernel. On the other hand, if grub-set-default were able to set a for-this-boot-only boot entry by itself, then why would the info page describe this sillier workaround? Joe -- gentoo-user@gentoo.org mailing list thanks for your help I will try that one.
