I regred for still having to suport several old centos servers during the last decade. Still regret of having to do lots of co-hosted old projects migrations from one of these – for lost time, money.
Have never regreted for any debian based one during the last 20 years. Have switched desktops ~10 years ago too. Before, been hardcore rpm distros fan – desktop: fedora, later suse; servers: centos, sometimes fedora. Lucky to have used deb distros for servers too, that made at least part of the bussiness stay stabile.
Argh, tired of that rpm’ers shit – paths differ, config locations differ, you got to learn relearn on each swich again.
As for deb distros, they been for me more stable in that concern – life long know-how reusability, muscle memory, old notes of shell snipets still valid. Decade old servers, current ones, LTS (long term support) desktop distro or last dev edition don’t difer much from point of view of fs organization and if differ at anything these are small evolutionary changes. My main argument reusability of know-how and “muscle memory” between desktop and servers and during the years, and growing reusable know-how during the years on top of that.
