[15:38] <bdmurray> ev: I've seen a fair number of people trying to install 11.04 on an existing 11.10 system.  Do you know what would happen there?
[15:38] <ev> no idea, beyond there not being a rollback option in the release upgrader
[15:39] <ev> it's an interesting statistic to follow though
[15:40] <bdmurray> there is one reference to seeing "upgrade Ubuntu 11.10 to 11.04"
[15:41] <ev> I suspect that wouldn't feed into the rationale for that many people
[15:41] <ev> I mean, if they put an 11.04 CD in a 11.10 system, chances are they wanted to do that (or format)
[15:41] <ev> only obviously it should be called downgrade or reinstall
[15:42] <ev> the latter being what the code should currently be doing - though if they're seeing this, clearly it's busted
[15:44] <bdmurray> I might run a test and see what happens so we can at least tell people to stop doing it.
[15:58] <ev> :)

[16:33] <bdmurray> it certainly says upgrade
[16:33] <ev> oops
[19:32] <bdmurray> ev, cjwatson: How could I recover my system in bug 891711?
