    <server>  is the name of a swift service e.g. proxy-server.

						|
              The '-server' part of the name may be omitted.
 | 
						|
              'all', 'main' and 'rest' are reserved words that represent a
 | 
						|
              group of services.
 | 
						|
              all: Expands to all swift daemons.
 | 
						|
              main: Expands to main swift daemons.
 | 
						|
                    (proxy, container, account, object)
 |

              rest: Expands to all remaining background daemons (beyond

 | 
						|
    <config>  is an explicit configuration filename without the
 |

              .conf extension. If <config> is specified then <server> should
 | 
						|
              refer to a directory containing the configuration file, e.g.:
 | 
						|
 | 
						|
                  swift-init object.1 start
 | 
						|
 | 
						|
              will start an object-server using the configuration file
