The cost of disk space seems to drop at a much faster rate than the cost of
bandwidth (which stands to reason, really); people may have DVD burners, but
the cost (to the mirrors, and to the users) of downloading full-sized DVD
images is still going to be significant for the foreseeable future, I think.
I also think we're still far from running out of cruft that we can squeeze
out of the CDs. There's still redundant functionality there - especially
where HTML rendering is concerned! - and having the hard upper limit on the
size of the base system is very valuable in getting developers to think
about creative ways to keep the size down without sacrificing functionality
(or, in the worst case, making hard decisions about which functionality
should be sacrificed in order to continue providing users with a
As a recent example, we recovered an incredible amount of CD space recently
(IIRC, 8MB vs. hardy, and 14MB vs. the most recent intrepid daily where we
were running into the problem) by doing the right thing with
libgweather-common. When we can still find 1-2% fat to trim with a single
cut, I don't think it's time to give up on fitting an OS on a CD.
As for whether we'll recognize when it's time to shift to larger media as
the default, I have no doubt. I expect there'll continue to be pressure
from the other direction, to remind us to revisit the question at least once
a release cycle. :)
