sub-optimal torrent for F9 Snapshot 1

[John Poelstra]

I'm finding trying to get Friday's snapshot of Fedora 9 to be very 
sub-optimal... 62 hours estimated to go after already timing out once. 
I've got two peers and one seed :(  I'll probably get it by time the 
next snapshot is ready :)

Is this happening to others?

Is this really a viable way to put out *weekly* snapshots?

Is hosting jigdo templates a possibility?  In my situation it would work 
well because I mirror the rawhide trees locally--yes I realize this begs 
the question of why I need the snapshot if I already mirror rawhide, but 
I'm curious if it fails to install for me just as rawhide has for the 
past three days.

Yes.

Nope. I canceled my download. My guess is that we need to do beta 1 beta 
2 etc in quick successions instead of this to get enough number of 
downloads going and subsequent feedback hopefully.

Not happening here, I'm adding another seed to the swarm - I see it's 
already uploading more then it's downloading, while it is still downloading.

No. ;-)

The snapshots (torrent ISO images) should have an updates.img which 
should make them installable.

Jigdo is a possibility in distributing the snapshots, but the downside 
is that at least one party, and preferably more then one, will need to 
keep hosting the slices; while on day 0 all slices are (or should be) in 
rawhide, on day 1 some packages might have been updated again and are 
thus not available anymore -unless some party keeps hosting the entire 
tree such as Fedora Unity does with their Re-Spins; 4 mirrors keep 
hosting all slices that come from the updates/ repository for as long as 
the Re-Spin is offered for downloading.

Kind regards,

Looks like this is actually releng's call as they decided to host jigdo
for the last beta.  I'm not sure if we ever got it actually working right
though.

As I mentioned in other threads, jigdo requires that the slices be
available via http somewhere.  The amount if time we have to spin a
snapshot and get it somewhere public for it to have any sort of
relevance is pretty darn short, and trying to instasync a number of
mirrors hasn't gone too well in the past, and those mirrors would just
quickly become overloaded and not able to handle jigdo requests anyway.
(there are those that would just http mirror things instead of using
jigdo).  So for the most reasonable turnaround time, we use torrent.  We
can upload isos in a matter of hours and start the torrent system.
Theoretically I can seed as well as I just did the compose, and we might
be able to seed a few other places that have fast access to the
snapshot.

We'll keep thinking of better ways to deliver the snapshots, it's just
quite difficult to do something with fast turnaround /and/ have a way to
spread the delivery load.
