Debian should make some serious money with 'Licensed for Debian' badges
I would suggest that Debian makes money by selling 'Licensed for Debian' badges.
When we look to buy servers we generally use HP because they are very supportive of Debian. However, due to costings we sometimes get other brands.
Whenever we look to buy a particular model we have to do the 'Will it run Debian' searching around. For example - I've bought a Fujitsu Seimens today - and had to check a possible NIC driver issue.
What I suggest is that FS should send a server to Debian for authentication. Debian could then check that the server will install Debian stable and all hardware runs properly. If it passes then FS would be able to apply a 'Certified with Debian' logo and pay for a sticker for each machine.
This could also apply to other bits of kit like RAID cards, gigabit NIC cards etc
I'd love to be able to go to online stores and be able to easily select kit which I know will work with Debian - surely it will be worth it to the manufacturers to get some extra sales.
