eth0:1 did not come up automatically

eth0:1 isn't an interface. As far as I'm aware, ifupdown doesn't support
aliases directly, so you can't just add a stanza for it in
/etc/network/interfaces. But I may need to be corrected on this.

I've always done something like:

auto eth0
iface eth0 inet static
	address 192.168.0.84
	netmask 255.255.255.0
	network 192.168.0.0
	broadcast 192.168.0.255
	gateway 192.168.0.1
	# dns-* options are implemented by the resolvconf package, if installed
	dns-nameservers 192.168.3.65 192.168.2.65
	dns-search example.net
	up ip addr add 192.168.0.80/24 dev eth0 label eth0:1
	up ip addr add 192.168.0.249/24 dev eth0 label eth0:2

(label eth0:{1,2} are only needed for backwards compatibility with
ifconfig)

But perhaps there's a better way?
