I tried to gather the pros and cons of the transition:
- more backports, mostly drivers but also some "core" functionality
- some non-critical fixes that were too intrusive for a maintenance update
- longer regular support
- current users might encounter some problems (like need to rebuild 3rd party modules)
- SLE12 is more mature after more than year, SLE12-SP1 will be relatively fresh
What factors go into kernel choice besides these? I know Fedora is considered bleeding edge by many, very much in constast to openSUSE's more moderate policy, yet I'm puzzled how openSUSE kernel updates policy can be so vastly different from Fedora's.
openSUSE 13.2 was released last November with 3.16.6, and has only 3 versions in /update/, having just reached 3.16.7-24 mere hours ago.
Fedora 21 was released about a month later with 3.17.4, subsequently updated to 3.18.x, then a series of 3.19.x, then a 4.0.x series, and latest is 4.1.4.
I have a bunch of 13.1 installations, about half on 3.11, the rest on your 3.12. I can't tell any difference.
I can't help but think that given any two kernel X.XX choices that the newer would be a no-brainer. Who's getting shafted by running Fedora? It seems like Evergreen might be candidate for a kernel updates policy more like Fedora's.
