No Fedora doesnt at all have livepatching. I think APT distros are great at not needing reboots, Fedora sucks. Its offline installer doesnt work well enough to excuse the reboots.
Fedora Atomic Desktops meanwhile offer awesome unbreakability. I use Kinoite daily and dont plan on switching. Even though using latest Plasma, it just doesnt break.
I would choose a different Distro though, if I didnt want rpm-ostree. Just not sure what? Kubuntu? No. Arch? Hell no. OpenSUSE Slowroll with KDE probably, yes that would be it.
