On the other other hand, you can test upgrades at any time, with dnf- system-upgrade. We're already testing 22-24 upgrades daily in openQA at present. > On the other hand, there is no prohibition against a fix after EOL. There is, in fact; you can't push updates for EOL releases, it's simply disabled by policy. > We also do not know there will be serious problems.

This is basically what I'm saying: we can't actually make any guarantees about *most* upgrade experiences, and N-2 upgrades aren't really some special case which is massively more likely to go wrong than any other. Will we have people who have issues doing N-2 upgrades? Probably, sure. Do we have people who have issues doing N-1 upgrades? yep! This isn't something new. We *do*, I think, mention in all the relevant documentation that upgrades are complex operations and success is never guaranteed, that's not what 'supported' means, especially in this context. > As far as I know, this is the first time "dnf system-upgrade" has been > generally available for a release-skip upgrade.

But it's really not hugely different from fedup - it's just an even lighter implementation of the same basic idea (just boot to a minimal environment and run a dnf transaction). The experience of fedup should be a reasonable indicator of future dnf- system-upgrade experiences. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@xxxxxxxxxxxxxxxxxxxxxxx
