Frisbee/imagezip
I created a page in the zimage wiki that has a patch for imagezip along with updated frisbee software. Click on the zimage wiki link or this link: linux stuff.
Frisbee is a Norton Ghost like program for Unix/Linux. Very nice little program. Support multicasting and intelligently compressing ntfs, ext2, vfat, and ffs filesystems.
I would eventually like to get this scripted out a bit more. Not going as far as emulab.net… something a bit smaller scale.
