wpa_cli will also work; if anyone's interested, I've written a shellscript
based on dialog that simplifies configuring wpa_supplicant.

Said shell script is actually part of my local wireless configuration
setup; the other half consists of an init script to start wpa_supplicant
and a script to call busybox udhcpc when the connection is completed.

If you're wondering how wpa_cli connects to wpa_supplicant, it's by
means of a unix socket at /var/run/wpa_supplicant/$IFACE; no DBUS
involved.

Ah, that's where the fun *starts*! It's all boring till you get there.

Just purge the dbus package; it can be done, and it won't break anything
that wouldn't be broken by stopping dbus.
Then pin it (at -100, maybe?).

Apt does that for you if you purge dbus.

ALSA does not use dbus.
It uses a library that handles writing to the soundcard.
I've used a Debian system that has ALSA and not DBUS, as well as running
strace.

Or just add the MirDebian repos that Miroslav referred to (you may want
both yplentyn and wtf).
There are no dependencies that are missing on Devuan, since everything
that we're trying to remove is a subset of what mirabilos set out to
remove.
