I upgraded from Fedora 14 to 16, recently. I had two static IP v4 addresses configured on my ethernet interface by creating two files in /etc/sysconfig/network-scripts:
ifcfg-eth0 -> first address ifcfg-eth0:1 -> second address
After the upgrade, this resulted in an error message during the boot process and in only the second address being successfully configured on the interface. So, what is the correct way to configure multiple addresses on a single interface on Fedora 16? I could not find anything on this subject in the documentation so far.
