Title:
  Cant add multiple ipv6 addresses to an interface

Status in “ifupdown” package in Ubuntu:
  Confirmed
Status in “ifupdown” package in Debian:
  Unknown

Bug description:
  Binary package hint: ifupdown

  Ubuntu:	    10.04.1 LTS
  Kernel:	    2.6.32-22-server   (i386 & x86_64)
  ifupdown:   0.6.8ubuntu29

  Here The inital version of "/etc/network/interfaces"
  -------------
  auto eth0
  iface eth0 inet static
          address 192.168.5.2
          netmask 255.255.255.0
          gateway 192.168.5.1
  iface eth0 inet6 static
          address 2001:db8::a
          netmask 64
  -------------

  You cant add multiple ipv6 adresses directly to eth0, so i created a new IF:
  -------------
  auto eth0:0
  iface eth0:0 inet6 static
          address 2001:db8::b
          netmask 64
  -------------

  After a "/etc/init.d/networking restart" i'll get an Error:
  -------------
  SIOCSIFFLAGS: Cannot assign requested address
  Failed to bring up eth0:0.
  -------------

  As Workaround i added an ipv4 dummy address to the IF eth0:0:
  -------------
  auto eth0:0
  iface eth0:0 inet static
          #dummy
          address 192.168.66.6
          netmask 255.255.255.255
  iface eth0:0 inet6 static
          address 2001:db8::b
          netmask 64
  -------------

  Now the "/etc/init.d/networking restart" returned no error,but all ipv6 addresses are on eth0 directly (ifconfig):
  -------------
  eth0      Link encap:Ethernet  Hardware Adresse 6c:f0:49:d0:3a:65
            inet Adresse:192.168.5.2  Bcast:192.168.5.255  Maske:255.255.255.0

  In my opinion thats no proper handling.
