I want to run udhcpd on an aliased interface eth0:0

I modified /etc/udhcpd.conf interface config line like this:
interface       eth0:0    #default: eth0

But when I run udhcpd it fails aright away:
[root at ST600 /]# ifconfig eth0:0
eth0:0    Link encap:Ethernet  HWaddr 24:DB:AD:00:12:4B
          inet addr:10.0.54.51  Bcast:10.0.54.63  Mask:255.255.255.192
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

[root at ST600 /]# udhcpd -f /etc/udhcpd.conf
udhcpd: can't bind to interface eth0:0: No such device
[root at ST600 /]#
