the tool zsync was not developped to support ssl, but there's a build that includes it, but i don't see any source code (if i remember correctly that this was the problem) to compile / package it for elive
it depends of if you want the new features and they are NOT automatically included in your elive, which they are:
- from apug
- from elive-upgrader special features (this one and the previous one are made automatically in your system)
- from "elive-skel upgrade" to update confs (like the updated one of conky)
- or from the installer, which includes things that cannot be included from the previous ones (like new kernel, or a different packages selection)
