[3dem] Operating system for local server environment

[Grigory Sharov]

Dear Christian,

I personally have experience with [X/K/U]buntu, Centos, and some Arch
> Linux, so I am aware of the basic differences (e.g. apt vs yum).


If you are going to manage this server then this is your answer. Use the OS
that you have most experience with.

I wouldn't use Arch Linux for a server (it is mostly for "bleeding edge"
desktop enthusiasts) and if you go for Ubuntu, in my opinion a server does
not have GUI, so no X/Kubuntu. Personally, I'm not an Ubuntu fan and use
Debian.

Proposed by cryoSPARC is Ubuntu, at some other point (might be in the

CentOS has been buried by Red Hat/IBM, so Rocky linux, Alma linux or
VZlinux are the alternatives currently being developed by the community.

Hope this helps,
Grigory
