## If auditd is sending or recieving remote logging, copy this file to
## /etc/systemd/system/auditd.service and comment out the first After and
## uncomment the second so that network-online.target is part of After.
## then comment the first Before and uncomment the second Before to remove
## sysinit.target from "Before".
## If using remote logging, ensure that the systemd-update-utmp.service file
## is updated to remove the After=auditd.service directive to prevent a
## boot-time ordering cycle.
