LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
JOB    = Pending job for the unit.

28 units listed. Pass --all to see inactive units, too.
[2] Stop a service. The example below means stop 'sendmail' and disable auto-start at booting system.
[root@dlp ~]#
systemctl stop sendmail.service

[root@dlp ~]#
systemctl disable sendmail.service

rm '/etc/systemd/system/multi-user.target.wants/sendmail.service'
[3] There are some SysV services on Fedora 17. Those are controled by chkconfig like below.
[root@dlp ~]#
chkconfig --list

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.
