The problem with using Fedora, non-LTS Ubuntu, and maybe OpenSUSE is that there is always a compelling reason to upgrade: continued support. You've got maybe seven months to go on Fedora 11.

A Fedora version is unsupported approximately 13 months after release. After that, no more updates. How well are Fedora/non-LTS Ubuntu releases supported in the period between the new version being released and the end of support? Do they get anything besides security/major bug fixes? Do they get kernel upgrades / backports? How well do upgrades work when skipping between versions?

Since Linux drivers are often only provided for the latest or recent mainline kernel version(s), one may have to upgrade, rebuild parts of the system, or backport drivers if they change hardware / need improved drivers. And after a few years, new software might not work with old dependencies. (For example, Firefox 3 won't build out-of-the-box using the libraries included with RHEL 4.)

I personally use CentOS to avoid these problems - Red Hat provide updates for years, and backports drivers and fixes.

I doubt RedHat supports CentOS unless you pay them too.

My guess is they usually only support RHEL.

Well, it seems in this discussion 'support' is shorthand for 'patch and security support'. I don't think anyone was implying RH is supporting CentOS in the trouble-ticket sense. In any case, CentOS 5 will be 'security supported' until March 2014, which is a longest available right now (I think).

How well are Fedora/non-LTS Ubuntu releases supported in the period between the new version being released and the end of support? Do they get anything besides security/major bug fixes? Do they get kernel upgrades / backports? How well do upgrades work when skipping between versions?

Firstly, as someone who has administered business desktops using both Fedora and non-LTS Ubuntu, I would not lump them into the same category. Both do get security and bug fixes. Fedora takes a rather cavalier attitude regarding kernel upgrades. Over the (short) lifetime of a Fedora release, one might see 3 major kernel upgrades. For example, Fedora 8 was released with 2.6.23. 2.6.24, 2.6.25, and 2.6.26 crashed our XDMCP server about once a week, bringing down about 70 users. (Yes, I gave each version a try. All Fedora kernels killed it right up to the point at which we switched to another distro.)

Ubuntu (non-LTS) takes a more conservative approach. If the distro releases with, say, 2.6.31, then 2.6.31 is what it will be for the 18 months that the version is supported. As an admin I find this to be a blessing. I'm uncertain whether drivers are added over the life of the kernel. I suspect they are. But I don't care that much about that in this use case.

The Fedora update pipeline is a firehose. Ubuntu's updates are much more controlled. I get the impression that you might feel that continued, aggressive updates are always a good thing. The admin in me shudders at that thought. But it also shudders a bit at the idea of being stuck with old tools for extended periods, which is why I use CentOS judiciously, and not for everything.

Non-LTS releases don't get new drivers AFAIK and I am not sure that even LTS releases do get a lot of backports. Red Hat and Novell certainly do a lot more in that regard.

Any Ubuntu kernels devs around that can correct me?
