I remember discussing this with Mark way back before Warty released. We
decided at that point that we would not do point releases of ISO images
as a matter of routine, partly for the sort of reasons you outline
above, and partly because unless we were very careful it would introduce
significant confusion for consumers of CDs received through shipit as to
what exactly they were getting.

That policy hasn't changed in the intervening years, although we will
shortly be doing a point release of Ubuntu 5.10 to address a password
disclosure vulnerability in the installer itself (which has also been
worked around in security updates, so don't panic, you aren't vulnerable
if you're up-to-date; we just think it would be a good idea to fix the
installer too). That's pretty much the only scenario in which we'd
envisaged doing point releases up to now.

I wouldn't like to rule out point releases of Dapper. That's a special
case because of the long-term support.

For what it's worth, I do not recall the kubuntu.de folks ever coming to
me as the cdimage admin asking for point releases. If they had, I could
have told them the above and they would not have needed to put it in a
ransom note on their web site.
