Sometimes I think you just like to argue with me.
I didn’t invent enterprise life cycle planning. Virtualmin supports specific distributions for a specific time period; to keep it simple, it exactly mirrors the life cycle of the distribution in question. We choose long-lived distros (e.g. only LTS Ubuntu, and not Fedora) to support, because that’s what most sysadmins and businesses want, and they want to know how long Virtualmin will be supported.
You’re arguing we should randomly change that on a whim, and on no notice…Why? What good could possibly come of cutting people off during the last month or two of the distribution’s life? As long as the distro is supported by the upstream vendor, we will support Virtualmin on it. Period. That’s the assurance we give to businesses that rely on Virtualmin.
I love to see old distros go away, as it makes our job easier and the systems get nicer with time (generally, though sometimes horrible ideas like FirewallD show up in newer versions). But, I also recognize that many folks don’t have the spare time to upgrade production servers that are working as they’re supposed to, just because there’s something new out there. If the distro is supported, that’s fine.
