That tool isn't good enough. Here is what vrms says about one of my machines:
jester:~# vrms
No non-free packages installed on jester! rms would be proud.
One little problem... jester is a fully functional MythTV front and backend. It can rip and play DVDs, play video and music in a multitude of patented formats, etc. RMS would not be proud of that machine.
