If we take stability as a parameter, is it safe to match them like this?
Fedora --> Ubuntu
CentOS Stream --> Ubuntu LTS
RHEL --> Debian
I know that CentOS stream is more kind of a rolling release but... feels like an LTS distro in practice... or it is just me?
Edit: adding some context.
I am planning to setup a dev machine that I will connect to remotely and would like to babysit very little while having stable and fresh packages.
In the Ubuntu world we would go to an LTS release but on the RPM/Dnf world is there any other distro apart from CentOS Stream?
And also is CentOS Stream comparable to an LTS release at all considering that they do not have release number?
IIRC, within RHEL it goes fedora (next major) -> centos stream (next minor) -> RHEL (current major.minor).
With Debian and its derivatives (e.g Ubuntu) this means that Debian-unstable corresponds to fedora, Debian-testing corresponds to CentOS stream and Debian-stable corresponds to RHEL. (Roughly of course).
Ubuntu is based off of some flavor of Debian and is therefore downstream of it: Debian (unstable I think) -> Ubuntu -> Ubuntu LTS.
But as far as which version has the newest packages then sure, your list is correct.
