Bug 521848

Description of problem:
According to Fedora initscript guidelines ( https://fedoraproject.org/wiki/Packaging/SysVInitScript ), there are few minor buglets in nscd's initscript.

Version-Release number of selected component (if applicable):
nscd-2.10.1-4.x86_64

How reproducible:
always

========================
case 1) Starting already started, and stopping already stopped nscd actions report [FAILED] and return code 1. According to the guidelines, these actions should be considered success and 0 should be returned. 

<quote>
For all other initscript actions, the init script must return an exit status of zero if the action was successful. In addition to straightforward success, the following situations are also to be considered successful:
    ( ... )
    * running start on a service already running
    * running stop on a service already stopped or not running 
</quote>

Example:
# service nscd start; service nscd start; echo $?
Starting nscd:                                             [  OK  ]
Starting nscd: /usr/sbin/nscd: already running
                                                           [FAILED]
1
========================
case 2) condrestart, try-restart actions report return code 1 and failure when the action is attempted on stopped nscd. According to the guidelines, this case should be considered success and 0 should be returned as RC.
