BTW, two other things I'm wondering about ifup/down:- when an interface is really down (as seen with ifconfig), why does ifup refuse it's operation saying "device already configured"? It could determine that
- when removing an ethernet card from a pc laptop, the interface goes away (but does not trigger ifdown). When reinserting it, the interface does not come back. (One has to manually issue "ifdown eth0; ifup eth0").
