On Ubuntu there's zsh support for command-not-found too (users need to source the file manually) so it's Good Thing to have zsh support on our implementation --Willwill 09:44, 24 July 2009 (UTC)
IMHO, this plugin must not try to download anything from network. Consider a new system install without any yum cache, which is connected to Internet with a slow connection. Then, just consider the case that the user types a command with some spelling errors. He'll see a command not found message, and then he should wait... and he might need to wait indefinitely (completely possible due to bug #515744) or press Ctrl+C. Doesn't seem to be a good setup. I think that this plug-in should work completely offline (or at least like when you run yum with -C commandline) or it will make Fedora even more frustrating for such users in its package management system. -- Hedayat 07:18, 20 Aug 2009 UTC
