Yep, I got bit by this once when I did updates and then something (don't know what) happened that caused the grub2.cfg update (pre BLS) to still be in the XFS log. The system would just boot to a grub prompt... I was on a trip and sitting in a hotel room (so no access to another system, a rescue USB drive, etc.), and basically hadn't had to mess much with boot loaders in a long time, so didn't really remember any GRUB2 commands. I eventually puzzled out enough to get the system booted, but it was a bit of a pain. The ideal solution would be for the GRUB2 (or any boot loader) FS drivers to be able to do journal or log replay in a memory overlay (no writes to the disk, so if there's a problem the boot loader wouldn't make it worse), but that's a very non-trivial exercise, plus could take a good bit more RAM. -- Chris Adams <[email protected]> -- _______________________________________________ devel mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
