[svn_mapguide at osgeo.org]

Author: jng

New Revision: 8969

Modified:
   trunk/MgDev/Server/src/Core/mapguidectl
Log:
#2527: Improve mgserver service control script:
 - define log_end_msg if not defined in lsb functions (as in CentOS 6)
 - define status and restart actions
 - exit with failures if something goes wrong
 - warn user if trying to start MapGuide and it is already running
 - warn user if trying to stop MapGuide and it is not running
 - No bash-isms, allowing it to work in base un-configured Ubuntu (whose default shell is dash, not bash)

Patch by Gabriele Monfardini, tested by me.
