+# 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.
+#
+# chkconfig: 2345 47 76
+# description: IPsec provides encrypted and authenticated communications; \
+# KLIPS is the kernel half of it, Pluto is the user-level management daemon.
