if in /etc/default/grub you have the entry GRUB_ENABLE_BLSCFG=true
that inserts a line into the grub processes to use the new BLS standard,=20
in which case grub2-mkconfig and possibly grubby do nothing until that=20
entry is set to false. I have always use grub2-mkconfig because I have=20
never liked what grubby generated, and what BLS generates appears to be=20
the same as what grubby does, and I found that I had to set that entry=20
to false for grub2-mkconfig to continue to work.
THANKS FOR THAT, Steve!
I could not get grub2-mkconfig to actually change the grub.cfg file. Now
I know why ( but not why such a dangerously misdescriptive switch would
be hidden away in a default file).
In the past I would just edit the damn file, but the new motherboard
uses EFI, and such hands-on fixing might lead to an undesired result!
