NAME
       asyncdaemon - start a BIOD server for asynchronous I/O requests

       created when the system is brought to init level 1 or higher.

ACCESS CONTROL
       Must be superuser to execute.

RETURN VALUE
       -1     An error occurred.  errno is set to indicate the error.

DIAGNOSTICS
       Errno may be set to one of the following error codes:

       EPERM     The process has no permission to make the call.

       EINTR     The process was terminated by a signal.
