SYS contains a system what permits to dump a existing instalation to a bootable reinstallable CD/DVD, what additionally to reinstall that system or exclusively can
install packages, and have also a tool for compile from source-code progs and pack them. Correspondingly, also the system itself what's packed on the install CD, is a
good working mixture of .tgz , .rpm packages and own compiled progs (very similar to
the actual system running on my server, but somewhat cleaned up).
It is no live CD; the philosophy is contrary: in the time a life CD starts,
or worser even installs, one can already have installed a definitive system. Also, coming to Linux should be a little more determinated as with the live CD's. When you put in the install CD and booting, SYS installs within 12-18 min and asks nothing -- nor if one want it.
