My own quirk is that I dislike bloat. I've used Debian, and then Devuan for about 20 years, and I constantly strip out stuff that isn't necessary. Things like Avahi, which is installed by default, and appears to be a piece of software that runs constantly, waiting for me to buy a new printer. Consolekit claims to "keep track of seats". I have one seat. And so on.
Recently, I installed Devuan from scratch on an old laptop from the official ISO, and then spent about 2 days removing packages.
This led me to my current little project, which is to create a bootable image which has busybox, dpkg and apt-get, so that I can install a system by adding, rather than subtracting, packages.
