Darn. I'm going back and ask! :-)

I'm using the dhozac-vserver repo. Looking at
config-2.6.32-358.2.1.el6.vs2.3.0.36.29.6.31.x86_64

Well I'm going to embarrass myself by asking what should I see? And to
let everyone think I'm an antique collector I'll include the output.
# uname -a
Linux ns4.asisna.com 2.6.22.19-vs2.3.0.34.1 #1 SMP Mon Mar 17 05:32:04
EDT 2008 i686 i686 i386 GNU/Linux
I'm guessing the i686 and i386 are the giveaways.
And I don't upgrade very often. It works ... well!
