Most definitely, thanks for the interest in testing daily isos.

A number of the people who test isos are using the dl-ubuntu-test-iso
script:

  http://bazaar.launchpad.net/~ubuntu-bugcontrol/ubuntu-qa-tools/master/annotate/head%3A/dl-ubuntu-test-iso/dl-ubuntu-test-iso

from the ubuntu-qa-tools project:

  https://code.launchpad.net/~ubuntu-bugcontrol/ubuntu-qa-tools/master

It's a tad overcomplicated and somewhat hackish for what it does,
but it supports picking and choosing the various *buntus and flavors
(daily-live, alternate, dvd) as well as arches (though it doesn't
support arm varieties yet). It also attempts to use zsync first
and falls back to anonymous rsync access (which cdimages.ubuntu.com
supports) if zsync isn't available. At least a few of us run it out
of cron to keep our set of daily images up to date.

Ideally, it would integrate well with the testdrive tool:

  https://launchpad.net/testdrive

for quickly spinning up isos in VMs for testing, but no one's had
the time to take that on this cycle (that I'm aware of).

(I also had grandiose plans of adding jigdo support as well as support
for feeding into an apt caching daemon like apt-cacher or
apt-cacher-ng.)

You're obviously welcome to use and develop whatever tool you find
most convenient. Thanks again for the interest.
