"The rsync program is an FTP developed for Unix-based systems that provides rapid file transfer with a number of very handy characteristics that lend themselves to operating system installation. First, rsync can update whole directory trees and file systems. Second, the protocol can preserve file ownership and permissions. This combination enables administrators to set up model machines with customized file permissions, which can be replicated across a group of newly minted servers."
"SystemImager provides more robust security than the rsync utility on its own. SystemImager, however, cannot overcome the inherent bandwidth use limitations of its rsync foundation. Even on a Fast Ethernet connection, SystemImager tends to max out at 20 simultaneous systems, according to a speaker at the conference. This is because rsync sends all the image data to each server instead of using IP multicast technology."
"This second area is where new, interesting work is under way on SourceForge, the open-source development network spearheaded by VA Linux. Using a paper by Sally Floyd and others about reliable multicasting, a small group of volunteers--with no time frame for project completion--has begun work on Vaccine. Although the name implies an anti-virus concept, the project gets its name from the VA Cluster Computer Install Engine (sourceforge.net/projects/vaccine). The project is still in its infancy, but eWeek Labs believes developers are on the right track."
