I looked into it a few days ago and came to a fairly similar conclusion,
but wasn't confident enough in it to say anything to the mailing list.
But, everything I found agreed with what Kris said.  I also noticed that
if you set an interface alias to something that doesn't start with
"ifname:" the ifconfig tool completely pukes.  So, I think it's either a
problem with the "ip" tool, or whoever's architecting the networking API
in linux not specifying clearly what aliases should look like.  


Good find, I don't know how I didn't catch that.  For the curious,
here's what I'm getting:

$ sudo ip addr add 1.1.1.1/24 dev eth0 label eth0test
$ ifconfig
<eth0 information>

eth0test: error fetching interface information: Device not found


and it exits without any other information, while eth0:test will work fine.

Thanks,

P.S. Sorry for the dupe, Benson :)
