+#                            you must set up the chroot environment

+#                            doing this.
+#
+# OPTIONS="whatever"     --  These additional options will be passed to named
+#                            at startup. Don't add -t here, use ROOTDIR instead.
+#
+# ENABLE_ZONE_WRITE=yes  --  If SELinux is disabled, then allow named to write
+#                            its zone files and create files in its $ROOTDIR/var/named
+#                            directory, necessary for DDNS and slave zone transfers.
+#                            Slave zones should reside in the $ROOTDIR/var/named/slaves
+#                            directory, in which case you would not need to enable zone
+#                            writes. If SELinux is enabled, you must use only the
+#                            'named_write_master_zones' variable to enable zone writes.
+#
+# ENABLE_SDB=yes         --  This enables use of 'named_sdb', which has support
+#                        --  for the ldap, pgsql and dir zone database backends
+#                        --  compiled in, to be used instead of named.
+#
+# DISABLE_NAMED_DBUS=[1y]--  If NetworkManager is enabled in any runlevel, then
+#                            the initscript will by default enable named's D-BUS

+#
+# KEYTAB_FILE="/dir/file"    --  Specify named service keytab file (for GSS-TSIG)
+#
+# DISABLE_ZONE_CHECKING  --  By default, initscript calls named-checkzone
+#                            utility for every zone to ensure all zones are
+#                            valid before named starts. If you set this option
