On recovering from some crazy filesystem corruption, probably related to "thou shalt not resume from this hibernation image" (posts on linux-btrfs mailing list, I can share link if curious), gladly no loss of important data involved, I recreated XFS based /boot with xfsprogs-6.5.0 (12 Oct 2023) […] mkfs: enable reverse mapping by default (Darrick J. Wong) mkfs: enable large extent counts by default (Darrick J. Wong) After that GRUB started being funny on me: update-grub => grub-mkconfig and grub-install both told me: unknown filesystem grub-probe revealed that grub did not like to recognize new XFS based /boot filesystem. So /boot is Ext4 now. I don't really care. This is with grub 2.12~rc1-12 on Devuan Ceres. I read on internet that similar funny stuff happened as Ext4 gained features. Could this be the case here as well? Is this a known issue? I bet it needs a bug report to the GRUB developers? Sometimes I like booting to be simpler than that. *Much* *simpler* *than* *that*. With less moving parts that could do crazy things. Reminder to self: Don't start crazy experimentation adventures like "trying out BCacheFS with some 6.7-almost-rc2-i-dont-like-to-hibernate- kernel" (well the BCacheFS part of the adventure basically worked as expected as far as I can tell).
