It's not guaranteed to provide a fixed order any more, you should really 
look into udev rules or ifrename (there is something included in netcfg 
for this).

First of all, the whole connection types in the current netcfg are a bit 
screwed up and not all examples are correct. This should be cleaned up 
in the git version (which should have been released by now, but James 
said he had to document it first and then went MIA), and also the 
examples should be cleaned up.

About the actual problem: netcfg checks for the presence of a link and 
doesn't bring the connection up if no link exists. This is certainly 
useful for dhcp, but not so useful for static, as you have seen. IMO, 
this should be optional, but I have no idea if it changed in the git 
version.

Same point, the examples are bit of a chaos. I figured it out once, but 
I forgot which combination works. That said, it is possible :)
