Looks like we have this blueprint now, courtesy of Seb:

  https://blueprints.launchpad.net/ubuntu/+spec/desktop-q-one-iso-for-q

FWIW, the historical discussions of how we would size the no-longer-CD
images took place around this blueprint/UDS session:

  https://blueprints.launchpad.net/ubuntu/+spec/foundations-o-great-cd-debate

I was hoping to find information there about the intended timeline for
ratcheting up the limit; unfortunately that doesn't seem to be captured in
the whiteboard, possibly because it was overshadowed by the discussion of
shrinking the DVD.

Anyway, I bring this up because the hallway discussion at the latest UDS
seemed to converge on 750MiB (== 786MB) for the image size for 12.10, after
noting that 750MB is not much greater than our current 736MB.  But
effectively that's just kicking the can down the road a cycle, since we
would have the same question going from 786MB to 800MB.

The question is, over the long term does it make more sense to have images
sized in MiB or MB?  Is a 1GB USB stick really 1GB, or is it 1GiB?  Or does
this even matter, given that a) we want free space for persistence on a
typical USB stick, and b) 1GB USB sticks are increasingly rare because of
how small they are?

I'm personally fine with either 800MB or 750MiB (786MB) as a target for this
cycle, I just want to make sure we understand our trajectory for future
releases and that the limit in quantal makes sense as a point on that
trajectory.

Thanks,
