+# Attempt to add a set of static routes.
+#
+# Do this in "ipreallocated" rather than just "startup" because some
+# of the routes might be missing because the corresponding interface
+# has not previously had any IPs assigned or IPs were previously
+# released and corresponding routes were dropped.
+#
+# Addition of some routes might fail, errors go to /dev/null.
+#
+# Routes to add are defined in $CTDB_BASE/static-routes. Syntax is:
+#
+# IFACE NET/MASK GATEWAY
+#
+# Example:
+#
+# bond1 10.3.3.0/24 10.0.0.1
