[K12OSN] Fw: K12LTSP chroot Install Notes

[Jim McQuillan]

Jim,

This thread has a very low chance of dying.  I think it is more meant as 
a statement of the direction that Fedora is thinking about taking, 
rather than a question.

In september, several of us will be getting together to help get LTSP 
integrated into Fedora in a similar manner to how Ubuntu has done it.

Also, LTSP.org will be shifting more towards the way Ubuntu is doing it.

We'll have lots of info available after our face-to-face hack fest.

Stay tuned,

Jim McQuillan
jam at Ltsp.org
