 Releng say they dropped jigdo due to overwhelming indifference (the
 download numbers for the jigdo images were tiny).

When releng agreed to do jigdo, the proponents of it promised better tooling in 
the near future to create the jigdo data.  That tooling was never delivered, 
and the process to create jigdo data continues to be manual, arduous, error 
prone, and still difficult for clients to manage.

While I wasn't part of the decision to drop it, I wholly support the decision.

 Rsync should save almost exactly the same amount of bandwidth, since due
 to the way its algorithm works it will avoid downloading unchanged
 packages and download changed packages in full, just like jigdo. In
 addition you don't have to download a jigdo template file.

Hmm?  How will rsync compose me a .iso out of a bunch of rpms?

jigdo gives you the very same dvd image you can download.  There are
cases where this is important, for example when trying to reproduce bugs
from other people, or when running kvm guest installs with autotest.

Pungi should do the same, if you use only the release repo and the
kickstart from the spin-kickstarts package.

Havn't tried, but I doubt it.  Usually there always is some timestamp

autotest complains about the iso being the wrong one ...

 Perhaps  its useful - but about 4 minutes after installing noone has
the virgin install anyway ... so the usefulness is short-lived from a
bug reproducing / fixing stand ... so it value seems very limited to me.

I take it that Andrea meant to rsync the new iso over the old one (or a

Cat all your available new RPMs together into one big file with the same
name as the new ISO, and run rsync on that to convert it into the new ISO.

This is likely because we pull late fixes from a side repo when
composing the RCs, then push them to the official f16 repo by the normal
process; the time available is just too short to wait for an update push
and repo compose and sync every time we need to build an RC.

Yea, most users don't care probably.  Also note that the download page
never explained what these files are good for, so if you don't know what
it is you probably just skip over it.

is quite useful though.  A large fraction of the stuff in Packages/ is

Given the size of the jigdo files small download numbers are not a good
reason to stop that service IMHO.  Its not like we are saving tons of
mirror bandwidth ...
