I dropped a first-crack at a Dan's Guardian package for K12LTSP into the testing directory:
ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/testing/RPMS
Nothing fancy, just the bare-minimum amount of work required to get it to run. Note that this is the beta version of DG, not the production version.
I'll continue to refine the package/configuration over the beta period so that we should have it decently integrated by the time it reaches production quality.
