# ipsec		sysv style init.d script for starting and stopping

#		the IPsec security subsystem (KLIPS and Pluto).

#

# This script becomes /etc/rc.d/init.d/ipsec

# and is also accessible as "ipsec setup"

#

# The startup and shutdown times are a difficult compromise (in particular,

# it is almost impossible to reconcile them with the insanely early/late

# times of NFS filesystem startup/shutdown).  Startup is after startup of

# syslog and pcmcia support; shutdown is just before shutdown of syslog.
