I enjoyed reading the list of explicitly excluded software. My current approach to installing linux on a laptop is to start with xubuntu, add dwm, and remove the desktop, ibus, pulseaudio, and a bunch of other stuff. I discovered that Firefox will not play sound without pulseaudio! My next project is removing dbus, but many things on the system seem to depend on it. I think linux is a beautiful thing, but the mainstream distributions are messes of competing, redundant subsystems and massively bloated interface layers that do very little except make the system less reliable, slow, and hard to configure.
