Comment(by bdubbs@…):
I know this is an old ticket, but don't know if we should fix it or not.
First of all, the interface must be set 'up' before checking
/sys/class/net/${1}/carrier, otherwise an error is returned. Secondly, I
found that it takes about two seconds after the interface is set up for
the carrier to change from 0 to 1 for a static IP on my system.
I really don't want want to but a sleep into the boot scripts.
We could make the check optional in ifconfig.eth0 with a variable like
CHECK_CARRIER.
Also, I think this would only be applicable to wired connections.
I'd like to get feedback before continuing.
