As others say, where the use cases are so specific to each machine, it’ll be a headache juggling all of those images if your needs and workflow change down the road.
But I’d be remiss to say I don’t practice a form of what you mention, I would go insane if I actually had to reinstall from distro defaults. I have a single perfected VM image with customizations and software common to all of my machines. And yes, if you were to go this route, there are little quirks to iron out manually each time I image to a new machine, even old and well-supported ones. Some just cosmetic, some preventing graphical output. Although still much less time than setting up from scratch.
It works well enough for me, but it also frankly leads to a poorly-documented system that will accumulate cruft with updates, and can’t propagate changes in the VM to my existing systems easily, so I’m interested too to see what other people here suggest. Particularly for those niche customizations that land outside of /home and /etc (e.g. /usr/fonts, packages not provided by the distro).



Focus follows mouse and unchecking the option to auto raise the active window. Couldn’t live without it and being used to it has made me extremely clumsy when I do pick up my Windows work laptop.
I change the taskbar clock to be a one-line MM/DD HH:MM:SS format, drop in my customized locale (based on en-US for maximum compatibility, but without having to deal with US formats and units that I’m not fond of), and point the taskbar shortcut for my text editor to a script that creates a pre-named file and launches the editor with autosave enabled. Because having to manually save and come up with a name for your spur-of-the-moment notes sucks, automatically generating
20260831_text_1is so much better thana,b,a2, etc.XFCE specific, I get rid of the second panel full of launchers. Acquired taste, but also Chicago95 theme and icon pack.
