Just came along this stuff elsewhere about zsync saving time and band with new iso downloads,
-Question: It's possible to do the same with porteus?
We have now yet another way to get an up-to-date ISO without having to download the entire ISO (saves bandwidth and time). For example to get the latest April snapshot you could install "zsync" package and then run this command in your terminal in the folder where you have an older ISO:
CODE: SELECT ALL
zsync -i March_x64.iso http://iso.mxrepo.com/Snapshots/April_x64.iso.zsync
For March to April you save about 80% bandwidth/time.
For Official release to April snapshot you save about 70%
