Run with a custom SMACK domain (label).
Allows the systemd --system process to change its current
SMACK label to a predefined custom label (usually "system")
at boot time.
This is needed to have a few system-generated folders and
sockets automatically be created with the right SMACK
label. Without that, processes either cannot communicate with
systemd or systemd fails to perform some actions.
