Proposal to drop Ubuntu alternate CDs for 12.10

Thanks for the feedback.
We all understand that there are valid use cases that will not be addressed
as well in 12.10 without alternate CDs. But there is a real cost to
developing, QAing, and releasing these images; we don't get them for free,
and we need to ask ourselves whether, by continuing to maintain them, we're
missing out on opportunities to spend the time doing other things better.
For a long time, the team has already intended to drop the Ubuntu alternate
images once ubiquity's disk support was complete; and the Kubuntu developers
have indicated that they are thinking along this same line. The only
difference now is that I'm proposing we drop the alternate CDs while disk
support is one step short of "complete".
So we want to gather as much information as we can about how users are using
the alternate CD today and make sure we are directing users to suitable
replacements - or if there really is no suitable replacement, consider
whether those missing features are a sufficient reason to keep the alternate
CDs around. But RAID support alone is not likely to be sufficient reason,
given the range of fallback solutions I already mentioned.

If there are cases where the alternate CD boots and the desktop CD doesn't,
those are bugs that it's important to fix. Users should get a good
experience when they download the CD that they're pointed at on the
ubuntu.com website; having the CD fail to boot and then be pointed to
download a *second* CD is not a good experience. Nor is it a good
experience if they're handed a pre-pressed Ubuntu desktop CD and it fails to
If removing the crutch of the alternate CD causes users to actually *report*
the issues they're having with the desktop CD (because, btw, I'm not aware
of any outstanding reports that the desktop CD is not bootable), then that's
a *good* thing. And if there are bugs with booting the desktop CD, then
some of the developer time saved by not maintaining the alternate CDs can be
used to make sure those bugs get fixed.

Sorry, but I don't find this persuasive. First of all because there are
other ways to do the install that don't require you to assemble a degraded
RAID, if that's your concern; second, because when properly assembled, a
degraded RAID is no more dangerous than a non-RAID install; and third,
because at install time there's no data at risk because it's a fresh
install. So aside from the fact that all the other options for installing
RAID on a desktop are a little more cumbersome than the alternate CD, which
is already known, this really comes down to personal preference.

If you're doing a large number of installs, then you should consider setting
up a local mirror (or caching apt proxy) and using preseeding. This is
already best practice for large site installs, whether using alternate or
desktop CDs or netbooting.
