I agree. For example, target-generic-getty-sysvinit is still missing
from the list.

I see two ways to handle that automatically:

 * Have all those special targets starting with "target-" and have
   graph-depends exclude them automatically. Simple, but not nice if we
   have a real package named "target-<something>".

 * Instead of registering all packages into the make variable called
   TARGETS, register them into a variable called PACKAGES, which will
   get appended (at the right place) to the TARGETS variable. This way,
   the 'show-targets' thing can be turned into a 'show-packages' that
   will only display the value of the PACKAGES variable. This solution
   is probably cleaner than the previous one.

What do you think?

Best regards,

Thomas
