I'm running aurora 2.99+ I wish I could tell you what that was without a
full package list; (one of my complaints about aurora--too many binary
packages, not enough version control)  Of course, debian/apt is worse,
yet on that front.

kernel is 2.6.23.1-26.5.al3

Cool. Keep them, or give to me. ;-)

Plan 9 is a research OS, like pure mach; not quite commercially useful.  
OSF/1 is mach plus POSIX+BSD+etc commercially useful interfaces,
developed by OS professionals.  I don't recall if the last 1.3 src had
64bit extensions. Several vendors had submitted 64bit patches, though.

advfs is from DEC. Didn't come from OSF. But its basically afs in a
local lvm.  ZFS might be better than all.

I know they are working on being able to use gnu tools, but still use on
sun tools. I have it running at home.
