Challenge is that we don't have a good schedule of when the Unity drops
are going to happen and what features are emerging when. The other
applications and products that work on top of Unity need to interface
with it need to get synchronized in some way, so that effective system
testing can occur. Having predictable times when we plan to release an
image is a forcing function, in that they at least keep us focused on
making sure we have system testing going on and that the community
flavors, that are part of the Ubuntu project, can system test their
emerging bits on the evolving infrastructure with some degree of
Additional system testing and snapshotting of images at more than just
the currently scheduled points would, of course, be very welcome and
help with improving the quality, especially early in the 6 month

+1 :) Big challenge for him and the QA team will be when the 12.04.1
testing has to happen in parallel with the quantal development testing.

Am trying to think about what makes sense to keep around, and across
which products, and for how long, but if we can secure the disk space
for this, agree it would be useful to the developers and testers.
Preliminary thoughts are:
* Try to keep all image that we characterize (ie. run system tests on,
get boot speed measurements, etc.) available for a *useful* period.
However since we'll never have infinite disk space, ;) and they are less
useful over time, possibly some sort of age out strategy like:
* keep at least the last month's worth of these characterized images
available (ideally it would be nice to have a set of weekly ones ;) )
* keep at least a monthly snapshots from each of the 6 month
development period around for historical reference.
* keep these for all images that will be in the release manifest.
Seem reasonable? better ideas?
