I agree that it is a bug to make incompatible changes to the
grub-mkirescue CLI. But i also agree that this CLI is sub-optimal
in respect to future compatibility. It's just that i do not deem
sub-optimality a valid excuse for breaking interfaces.

Therefore my proposal to freeze grub-mkrescue CLI and to have
a new CLI with a new program name, while maintaining a common
backend for both CLI parsers.

What would be the advantage of using argp for the old CLI ?
The C version of the old CLI has the goal to be as compatible
as possible. It is straightforward to translate the shell code
of grub-mkrescue.in into equivalent C code.

-------------------------------------------------------------

Regardless which parser implementation gets chosen, there remains
the problem of the not yet implemented options from grub-mkrescue.in:

Are their use cases obsolete ?
Shall their valid use cases be covered by other tools ?


Have a nice day :)
