Fix for executing /etc/rc.d/network restart so it kills dhcpcd works ; however it now doesn't restart it.

[root@myhost paulr]# ifconfig

Correct, any dhcp-configured interface won't get an IP address after network restart and here is the explanation.
The network init script will skip any interface that is already up. And after /etc/rc.d/network stop, eth0 is still UP because killing dhcpcd does not bring an interface down.
I already proposed a fix for this issue in bug #6959.
See attached patch that works.

anyway, UP should not be made equivalent to inet addr, see  bug 7554 .

I think the problem of restarting and dhcp could be solved with just adding the "ifconfig ${1} down" right after the dhcp kill, don't know what it wasn't solved before.

Matt, this would prevent ifplugd (and others) to work at all, because downing the interface will prevent cable sensing. That's because UP != inet addr, and why my solution in task #7554 fits (IMHO) better.

Oh, ok. I understand. Hoped that 7554 gets attention then.
