Quoting Buck RHList@towncorp.net:
I don't remember where, probably the Fedora site, but I read that the goal of Fedora will be to produce a quality product on the bleeding edge but not a dumping ground for partial or non-working modules. (my terrible paraphrase).
That's good news. I'm sure the "Fedora Core" tag will further enforce that.
I suspect that Fedora will work well for a period of time, but maintenance on one version will cease upon release of the second version after it.
I read 2-3 months for "Fedora Core," giving people time to test, transition, etc...
It might be that it will be stable enough to operate for long periods but just not be protected from the vulnerabilities that may later be found.
And that's fine with me. People who need 1+ of support need to pay for it. There is no such thing as a free lunch, only free speech.
