Bug#864701: grub-common: grub-mkrescue does nothing, successfully

[J Mo]

Package: grub-common
Version: 2.02~beta3-5
Severity: normal

->grub-mkrescue -o asdf asdf
[~]
->echo $?
0

asdf does not exist -- just random characters. grub-mkrescue seems to be broken. I was trying to make a rescue .iso image using a real input directory but that was failing. After awhile I figured out that grub-mkrescue would just exit 0 without doing anything at all.

This command was in a script that I've used before, successfully, but it's been at least a few years.
