Thank you for your kind reply, Vladimir. I failed to find the probe
command - I promise - I spent quite a few hours digging through the
source. As for the $((...)) and $[...] - I'll look into it.
It seems that my paltry contributions are not needed, after all.

I have written two small, simple modules to address limitations I found
in in Grub.
1. does simple arithmetic - nothing fancy. It's invoked by using
something like this:
insmod arithmetic
arithmetic --set fred --min 2 -- max 10 "1" "+" "2"
the operators supported are unary -,!; binary +,-,/,*,%,<,<=,<.<=,!=,==
--set works in the usual way. If the result is greater than --max, the
--min value is returned and vice versa; this useful for cycling round a
group of partitions in a round-robin fashion
Can you have a look if we can have bash syntax $((...)) and $[...] instead?
It's more compact and nicer.
2. diskinfo.mod introduces two commands: disklabel, diskuuid which
return the label and uuid of the specified disk partition. This is
useful where, having decided which partition, amongst several, to boot,
you can fill in the appropriate value in the "root=UUID=" or
"root=label=" Linux kernel parameter.
Have a look at probe command. Does it cover your usecase?
I looked for details on how to submit new modules, but failed to find
anything. How do I go about this?
Just send patches here.
