Another wild guess: Problem with filesystem labels or UUID's? Grub2-mkconfig uses one or the other of those to build grub.cfg.
No. It is not a problem with Grub. My problem is solely with the EFI entries in the flash memory of the machine BIOS (UEFI, actually). I write a boot order with "efibootmgr" command in Linux, and "something" else changes the order to something else that does not boot (because it prefers an ancient entry that can not call the current grub2 after it was patched for that vulnerability). I don't know what is that "something". A process in Linux, or the firmware of the machine. Probably the later. Anyway, all my disks and partitions have both UUIDs and Labels. Specially the nvme disk that holds the system and boots the machine. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
