However, it broke my mediatomb server because the NIC changed from em1 to eno1. Is this something that was expected? It certainly surprised me.It happened to a bunch of servers when I updated them from F22 to F23. Their NICs changed from p6p1 -> enp3s0. It was annoying because I had to boot each one with a display and keyboard and change the network configuration by hand. "predictable, stable network interface names" https://wiki.freedesktop.org/www/Software/systemd/PredictableNetworkInterfaceNames/
that is simple to solve forever * add "net.ifnames=0 biosdevname=0" to your kernel params * get rid of NetworkManager * rename your ethernet-devices in the ifcfg-files based on the MAC * survives yum-upgardes from Fedora 9 to Fedora 23 * nobody needs NM and that other stuff on static configured servers * frankly even with a DHCP wan-interface it works perfectlythe machine below has 16 network-interfaces and the IP is configured via DHCP and after get rid of all the "improvements" no loger troubles
