The templates for both the DNS and DHCP services that are created when
clustering services in installed includes a number of definitions and
commands pertaining to mounting file systems.

#!/bin/bash
.. /opt/novell/ncs/lib/ncsfuncs

# define the IP address
RESOURCE_IP=a.b.c.d
# define the file system type
MOUNT_FS=reiserfs
# define the device
MOUNT_DEV=/dev/evms/dhcp
# define the mount point
MOUNT_POINT=/mnt/dhcp

# mount the file system
exit_on_error mount -t $MOUNT_FS $MOUNT_DEV $MOUNT_POINT

# add the IP address
exit_on_error add_secondary_ipaddress $RESOURCE_IP

# start dhcpd
exit_on_error /usr/sbin/dhcpd -cf $MOUNT_POINT/etc/dhcpd.conf -lf
$MOUNT_POINT/var/lib/dhcp/dhcpd.leases

# return status
exit 0

Is this necessary? I've been able to run a DNS cluster resource by only
defining and adding the secondary IP address and starting the DNS service
(rcnamed start). Am I losing some functionality by not mounting an
associated file system?
