zsync

[Phill Whiteside]

Hi Bob,

As far as I know, and I'm sure if I am wrong someone will correct me, zsync
is used to update the iso, so if you have a CD you would need to put it onto
the hard drive as an ISO and then zsync would simply update the parts of it
as the updates arrive, leaving you with a bang up to date ISO that you can
then use to create CD's / USB boots etc. The theory is that you do not need
to download the entire ISO again, it will simply just download ONLY the
files that have been changed (newer versions).

I've never used wget to try and update an ISO image, again I could be wrong,
but I do not think wget can perform that function.

Regards,

Phill.
