# ipsec         init.d script for starting and stopping
#               the IPsec security subsystem (KLIPS and Pluto).
#
# This script becomes /etc/rc.d/init.d/ipsec (or possibly /etc/init.d/ipsec)
# and is also accessible as "ipsec setup" (the preferred route for human
# invocation).
#
# 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.
