Testing in USB

Interesting. I haven't done much testing but 10.04 because I'd almost
rather take a beating than install a distro to suit my tastes.

If USB flash testing is good, I will have to take another look at it. I
have accumulated a significant number of flash drives, up to 16GB.  I
probably can't do dailies, because it takes too long to download.  But,
I can work on alphas and betas.

Thanks for info.
