| Pull kernel source, apply patches, build kernel, run kernel.

| Is there some literature on why this is? I'm curious. Is
| Fedora more "experimental"?
| doodlesdev wrote:
| Fedora does breaking point releases around every six
| months, and yes it's kind of more "experimental", generally
| speaking the repositories are as up to date as possible in
| a point release distribution, kernel version are always up
| to date, and Fedora is generally early adopter of breaking
| changes in programs such as GNOME, Wayland, Pipewire, new
| Wine versions, etc. Also Kernel updates are done mid-cycle
| which means this update could land even in just a few weeks
| from now.
|
| Meanwhile Ubuntu does a new LTS release once every two
| years, which are already somewhat outdated when they get
| released.
