# vinit - trigger the slice-local initscript as installed in /etc/rc.d/vinit.slice

# this is unconditionnally installed and activated in the sliver
# but of course nothing is run if the script is not present 
#
# note - for practical reasons this is *not* activated through chkconfig
# as the slice has not yet started at that point
#
# historical note
# historically planetlab initscripts have not been required to handle the 'stop' method
# so installing such a script directly as /etc/rc.d/vinit would result in the
# script .. being run a second time at vserver-stop time
