Comment 5 for bug 584758

By the way, the "Linux i686" part is already derived from "uname -sm".

I'm running Kubuntu Lucid and what I get with "uname --all" is:
Linux dave-laptop 2.6.32-22-generic
#33-Ubuntu SMP Wed Apr 28 13:27:30 UTC 2010 i686 GNU/Linux

I don't think the info you're looking for is in uname as stated. I'll just rename the bug to state the intent instead.

I agree with Philip that this is probably WONTFIX, not just because UAs aren't really for this but also because of plenty of other arguments in the other direction to limit exposed info for privacy reasons.
