eth0:1 did not come up automatically

[Arnaud Soyez]

Not sure if this will help, but here's how I did it on my server (don't pay
attention to the wrong addresses or masks...):

auto eth0
iface eth0 inet static
    address 192.168.1.31
    netmask 255.255.240.0
    gateway 192.168.1.1
    up route add -host 192.168.1.31 dev eth0
    pre-up iptables-restore < /etc/iptables.rules

auto eth0:1
iface eth0:1 inet static
    address 192.168.1.32
    netmask 255.255.240.0
    gateway 192.168.1.1
    up route add -host 192.168.1.32 dev eth0:1

auto eth0:2
iface eth0:2 inet static
    address 192.168.1.33
    netmask 255.255.240.0
    gateway 192.168.1.1
    up route add -host 192.168.1.33 dev eth0:2


And somehow,  auto eth0:1 ... wouldn't work properly, so i just added the
following to /etc/rc.local, to make sure they are brought up:
ifup eth0
ifup eth0:1
ifup eth0:2
