I did everything except this:

The problem with command -v is that it picks up aliases, which we
definitely don't want (in the incredibly unlikely case that grub-
mkimage has an alias).  You can see the effects with ls which I've got
aliased:

jejb@jarvis:~> command -v ls
alias ls='ls -F'
jejb@jarvis:~> which ls
/bin/ls

We definitely want the latter behaviour in the script above ... I need
the absolute path to the command, so I kept the which.
