I have an old Ubuntu 14.04 system that has Virtualmin on it that has to be upgraded and they don't want to have to reinstall the entire OS every time the OS stops getting updates like that. So I figure maybe if I can put an OS that uses a rolling release model on that might solve it. Any thoughts on that?
I thought Manjaro looked good but it's based on Arch which isn't one of the OS on the list. https://www.virtualmin.com/os-support.html
The other OS in the Grade B section on the list that say they have rolling release on DistroWatch are Gentoo and openSUSE.
And FreeBSD 13 but that looks like it's still in development so I'm not sure if it actually is rolling or just says that, similar with NetBSD.
So I'm guessing maybe the best options would be Gentoo or openSUSE which I have no experience running Virtualmin on. openSUSE looks more popular but that doesn't necessarily mean it works better.
Does anyone have any experience with those or are they known to work properly or have issues? Which one would be the best to use? Or am I thinking about it all wrong?
