Installing specific things both from the repo and from elsewhere (Minecraft), Minor UI tweaks - move the panel to the left side (wide monitor), Konsole settings for colors, font(dotted zero), font size (bigger), 80x25 window. Probably others but that’s all I remember for now.

Even for a home system? Not a fleet of data center servers. I am currently using rsync to backup /home/<<user>>/ to the ssh server. I tend to make a lot of changes to the base Debian/KDE install.
