I am browsing the shepherd's info docs, and I can't seem to find a way to run something right after either reboot, or halt were invoked. Something that is usually achieved by sticking a script into /etc/rc0.d in classical init systems, or /usr/lib/systemd/system-shutdown in systemd. Can I somehow configure this from my system-wide config.scm? Or any way at all, if that's not an option? My particular use-case is unloading a faulty kernel module, that prevents powering off the laptop right before shepherd actually tries to shut it down.
