NAME
launchd — System wide and per-user daemon/agent manager
SYNOPSIS
launchd [-v] [-s] [-x] [– command [args …]]
DESCRIPTION
launchd manages daemons, both for the system as a whole and for individ-
ual users. Ideal daemons can launch on demand based on criteria specified
in their respective XML property lists located in one of the directories
specified in the FILES section.
When run with a command, a specific instance of launchd is created and
the command is implicitly added to the list of jobs maintained by
launchd. If the command exits, that instance of launchd will clean up
all jobs maintained by itself and exit. All children of the command will
use that instance of launchd.
During boot launchd is invoked by the kernel to run as the first process
on the system and to further bootstrap the rest of the system.
OPTIONS WHEN RUN AS PID 1
-v Verbose boot.
-s Single user mode. Instructs launchd to give a shell prompt before booting the system.
-x Safe mode boot. Instructs the system to boot conservatively.
NOTES
In Darwin it is preferable to have your daemon launch via launchd instead
of modifying rc or creating a SystemStarter Startup Item.
At some point in the future, we hope to completely phase out the use of
rc.

NAME
nfsiod — local NFS asynchronous I/O server
SYNOPSIS
nfsiod [-n num_servers]
DESCRIPTION
Nfsiod runs on an NFS client machine to service asynchronous I/O requests
to its server. It improves performance but is not required for correct
operation.
Unless otherwise specified, a single server is started.
The options are as follows:
-n Specify how many servers are to be started.
A client should run enough servers to handle its maximum level of concur-
rency, typically four to six. Each server runs as a separate thread
within the nfsiod process.
The nfsiod utility exits 0 on success, and >0 if an error occurs.
