Details:
I'd like to ask for very basic arithmetic functionality for the scripting
engine of GRUB, mainly addition / subtraction, maybe even some more by e.g.
taking over code from `let` or the `$((..))` syntax from *sh.
Very concrete use case would be a typical ping-pong scenario:
Counting (failed) boot attempts, storing them in the GRUB environment block
and switching to a failsafe / second-system / you-name-it, once booting into a
system failed `n` times.
Yes, this can be done without arithmetic operation.
But apart from it "just not being nice" (however I think nice - as in:
readable - code is quite a point for the essential part of booting a system),
I can think of quite a few other scenarios where basic arithmetic would really
add to GRUB.
Thank you for having read my feature request till the end :)
