Poetterware is a type of software mostly found on Linux systems, for example systemd, pulseaudio, policykit, consolekit, xdg-open, colord and more.
This software generally works very well and solves really
complicated problems, but if it doesn't behave the way it should, you will have a hard time debugging the issue (e.g. via dbus), working around it (by quick hacks) or use
alternative software. It may be written by Lennart Poettering or the freedesktop
foundation or other participants in the ecosystem.
