<pre>If systemctl is used in a generator, it causes a deadlock which eventually
resolves when the bus connection request times out. But meanwhile, it prevents
systemd from starting up.
A generator like following will cause deadlock.
#!/bin/sh -e
. /etc/conf.d/iptables
if [ $IPTABLES_ENABLED = yes ]; then
systemctl --runtime --no-reload enable ip-filter.service
else
systemctl --runtime --no-reload disable ip-filter.service
fi</pre>
