event handlers - remounting smb shares

[Kyle O'Donnell]

write the logic into the event handler script.


pass the $SERVICEOUTPUT$ to the event handler

have the event handler check if the appropriate moutpoint has returned
the desired (or undesired) error

if condition mount
else echo wrong mount failure dont do anything.
