Agreed.

Agreed this is not user friendly heh...

Good point. Even though we may not list the other machines I think it
is expected those to me usable.

I am a bit unsure we ought to do a list by default. Maybe one more
user friendly way is:

* If no machine is set (using MACHINE=foo source ./setup-environment
build-foo), say to run ./setup-environment list-machines
* If user sets the machine, use it
* If user runs ./setup-environment list-machines, a list of machine
plus its verbose description might be output and use the 'more -d'
trick as EULA to paginate it.

Thoughts?
