[K12OSN] K12LTSP Server RAM question

[Terrell Prude', Jr.]

There are two solutions I can think of.

1.)  Install SuSE Linux Enterprise Server for AMD64 and install LTSP on 
top of that.
2.)  Install Red Hat Enterprise Linux AS for AMD64 and install the 
K12LTSP RPMs for White Box on top of of that.

I don't yet have a dual Opteron box (will be some time before I can 
afford one!), and therefore I haven't yet been able to test this.  
However, remember that the Opteron executes 32-bit code just fine, even 
when running in 64-bit mode.  Thus, even though the K12LTSP apps are 
32-bit, the kernel would be 64-bit and thus able to address all that 
memory above 4GB with aplomb.  Each individual 32-bit app will only be 
able to see 4GB, but if you really, really need OpenOffice.org to suck 
up 4GB by itself, then I'd like to come to work for you!  :-)
