I wrote most of this email > yesterday but didn't get to hit send until....now If you need people to test how Debian works on your new hardware, I'd be eager to help. If you need people to actually fix stuff when you know what is to be patched/uploaded, I'd be glad to review and upload the fixes on the archive. If you need a developer who could also do the integration part (debugging/fixing on his own), I personally couldn't guarantee that I'd succeed all the time. But feel free to reach out if you need hardware beta testers. NDA is fine with me. -- Pierre-Elliott Bécue GPG: 9AE0 4D98 6400 E3B6 7528 F493 0D44 2664 1949 74E2 It's far easier to fight for one's principles than to live up to them.
