Then CentOS would fit your server use case. The new CentOS is a rolling distro with smooth upgrades, most kernel patches don't need a reboot, live patching works.

> CentOS Stream defines Enterprise Linux.
> CentOS Stream is derived from Fedora Linux. It has a new major version release every three years, and each release is maintained for five years, matching the full support phase of RHEL. CentOS Stream development is open to all, but because CentOS Stream only has updates intended for RHEL, it is maintained by the RHEL team.
