# Provides:          vmware-guest
# Required-Start:    $syslog $remote_fs
# Should-Start:

# Short-Description: VMWare Guest Daemon
# Description:       Starts the Guest Daemon for a VMWare Virtual Machine
#	vmware-guestd is responsible for automatically starting vmware-user. 
#	It does so by tracking the activity of an X session, discovering the 
#	environment and credentials used in the session, and starting vmware-
#	user with those credentials and that environment. When the X session 
#	disappears, vmware-guestd will also notice and stop vmware-user. 
#	Note that more than one running X session will confuse vmware-
#	guestd and autostart will likely fail.

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