---------------------------+--------------------------
 I installed tor on CentOS Linux release 7.2.1511 (Core) with the packages
 from epel-release.

 I then proceeded to configure the /etc/tor/torrc file, but i was not aware
 there was a service active so i tried launching tor from shell - seeing
 the RunAsDaemon directive.

 This is not the expected behaviour, i should have been told there was a
 service already running.
