I make a grub config to boot iso images which provide loopback.cfg. So
after some preliminary steps I run `configfile /boot/grub/loopback.cfg`
and it works as supposed.
The problem is I'd like to modify `linux`'s args used in `loopback.cfg`
(or its subsequent configs) without touching the iso images.
Speaking in bash terms let `linux` be a builtin and I want to remove
`quiet` from all calls to `linux`. Since functions override builtins, I'd
just override it with a function:
linux () {
local arg args=()
for arg; do
[[ $arg == quiet ]] || args+=("$arg")
done
builtin linux "${args[@]}"
}
Is there anything similar in grubscript (not in the approach, but in the
result)? I tried to create `linux` function, but the command still
overrides it when called.
