Default is yes (current behavior). This means that after start process will be run in background. When "no" is given, process is run in foreground with `exec` call, which replaces current process (ovs-ctl) with wanted ovs process (ovsdb-server or ovs-vswitchd).
This option is useful when running ovs-ctl inside docker container to make ovs* process to be a pid 1. Note, that with `--detach=no` database settings initialization is not done. db-version, system-ids are not set and transient ports are not deleted.
