In my opinion they aren't any less functional. I've even read that "tar -cpf - /|(cd /mnt; tar -xpf -)" manages to avoid going into a loop with regard to /mnt! I haven't verified this but I'm not surprised - GNU software is the way to go! The con regarding "cp -a" is that it's GNU cp. Versions on other systems fuck up symbolic links e. g. The pro regarding tar is, there is one on every system, and combining two tars with pipes works everywhere (to my knowledge). This makes tar ideal for scripts that must work on all platforms. > Can an unmounted(*1) root filesystem be successfully > mirrored, identical to the original, on a target partition with a new > filesystem -- using cp -a or the tar -cvf (*2) method? The answer is yes. Both can do that. > > Christopher W.
