i saw that.. but nevertheless it can happen. Eg, ifconfig ethx xyz etc
up will bring up that interface if you have an alias in modules.conf.
Looking at strace i can't see how (with eth1 aliased to dummy) i
can't even get this case to work, but it does work - RH network init
script depends on it iirc. And i think it's similar to ping.
very curious as how it works...

don't know how, but apparently ping -I /can/ cause the kernel to try
configure the interface. And even if it can't, that's just an
illustration of a problem in modutils - not ping.
