Bug#589532: grub-mkrescue

[ael]

I have just hit this problem with grub-mkrescue. xorriso was not
installed (I was using a netbook with no dc/dvd) but needed a usb
rescue disk.

I note that grub-common suggests xorriso and agree that it should not
depend on it. But is there any chance that the error message when
xorriso is not found could make it clear that "xorriso" is a missing
program/package rather than a missing file as I first supposed?
