mdadm/boot.md
Neil Brown b09510a58a - boot.md - change args to mdmon.
The argument parsing of mdmon changed in the recent update
   and we need to change boot.md to match.  bnc#653965

Short-Description: Multiple Device RAID

Description: Start MD RAID

RAID devices are virtual devices created from two or more real block devices.

This allows multiple devices (typically disk drives or partitions there-of)

to be combined into a single device to hold (for example) a single filesystem.

Some RAID levels include redundancy and so can survive some degree of device failure.

END INIT INFO

Source LSB init functions

providing start_daemon, killproc, pidofproc,

log_success_msg, log_failure_msg and log_warning_msg.

This is currently not used by UnitedLinux based distributions and

not needed for init scripts for UnitedLinux only. If it is used,

the functions from rc.status should not be sourced or used.

#. /lib/lsb/init-functions

Shell functions sourced from /etc/rc.status:

rc_check check and set local and overall rc status

rc_status check and set local and overall rc status

rc_status -v be verbose in local rc status and clear it afterwards

rc_status -v -r ditto and clear both the local and overall rc status

rc_status -s display "skipped" and exit with status 3

rc_status -u display "unused" and exit with status 3

rc_failed set local and overall rc status to failed

rc_failed set local and overall rc status to

rc_reset clear both the local and overall rc status

rc_exit exit appropriate to overall rc status

rc_active checks whether a service is activated by symlinks

. /etc/rc.status

Reset status of this service

rc_reset

Return values acc. to LSB for all commands but status:

0 - success

1 - generic or unspecified error

2 - invalid or excess argument(s)

3 - unimplemented feature (e.g. "reload")

4 - user had insufficient privileges

5 - program is not installed

6 - program is not configured

7 - program is not running

8--199 - reserved (8--99 LSB, 100--149 distrib, 150--199 appl)

Note that starting an already running service, stopping

or restarting a not-running service as well as the restart

with force-reload (in case signaling is not supported) are

considered a success.
