First of all: it’s fast. As in "fast like computers are supposed to feel" fast.
The creator of Grep once famously said, the best way to make programs fast is to make them do almost nothing, and this computer - which is running a little four-core ARM SOC - feels responsive and snappy in a way that _nothing ever_ does anymore.
Second, it is - for the most part - comprehensible. At least as far as I can make it, building on the shifting sands of Systemd's treachery and DBus' ersatz convenience.
