RE: [K12OSN] Preparing K12Linux F11



Terrell,

I think the case for LTS is as strong today as it always has been.  

I completely agree with you on including LTS 4.x in a Centros version.

Where I disagree with you is on legacy hardware being the driving factor.
Cost of operation is still the leading factor as far as I am concerned.
