+ <p>The <c>start_disabled</c> command operates on a service
+ regardless of if it's enabled/disabled or started/stopped. It
+ does this by first enabling it (regardless of if it' enabled
+ or not), then starting it (if it's not already started) and
+ then disabling it. The result will be a disabled but started
+ service, regardless of it's earlier state. This is useful for
+ starting services temporarily during a release upgrade. The
+ difference between using <c>start_disabled</c> and the
+ sequence <c>enable</c>, <c>start</c> and <c>disable</c> is
+ that all other <c>erlsrv</c> commands are locked out during
+ the sequence of operations in <c>start_disable</c>, making the
+ operation atomic from an <c>erlsrv</c> user's point of
+ view.</p>
