An alternative could be letting the distros depend on SOME_MACHINE ||
OTHER_MACHINE, or on !SPECIFIC_MACHINE, whatever is shorter under
certain circumstances.

All approaches have the problem that if you are looking for something
that has a disabled dependency, may it be a machine or a distro ("How do
I get an Ubuntu image?"), you will not find it in the menu. We may need
to extend kas menu by some search and a visualization of the deps of the
items that are found, just like the kernel does.
