[K12OSN] K12 install how to on top of Centos 64 bit 5.x

[William Fragakis]

A few thoughts:
1 - trying to install a k12ltsp on top of vanilla install requires some
intimacy with the finer workings of ltsp. If you have to remember how
you did it last time, you may want to stick to a stock install
2 - As mentioned elsewhere, PAE kernel 
3 - Since drives now run $30-40, it's worth doing a clone installation
(say, using dd) and sticking it on a shelf somewhere. Given what your
time is worth (or things you'd rather be doing), it's cheap insurance.
In fact, I recommend for businesses, since hardware is so cheap, just
build a clone machine and stick it in a closet (or have it synch up
nightly or even hourly to an active box). When an ltsp server could run
$1200-1500, it wasn't cost efficient. Now that you can buy a dual core,
couple gig RAM box for $300-400, it is. 

regards,
William
