== Consistent network device naming ==
 
 
Fedora 18 continues previous releases' use of '''biosdevname''' to set network device names in a deterministic manner. Ethernet ports embedded on server motherboards will be named <code>em<port_number></code>, while ports on PCI cards will be named <code>p<slot_number>p<port_number></code>, corresponding to the chassis labels. This feature may be disabled by passing <code>"biosdevname=0"</code> on the kernel command line, in which case, behavior will revert to using ethX names.
 
 
== firewalld replaces iptables ==
 
firewalld will be the default firewall solution for Fedora 18, replacing iptables.  firewalld can be configured on the fly without reloading, allowing connection states to stay unbroken when rules are changed. A DBUS interface allows applications to communicate complex or temporary needs to the firewall without requiring hand configuration by an administrator. Manual administration can be done with firewall-cmd. Documentation on firewalld can be found in the included manpages, firewall-cmd(1), firewalld(1), firewalld.conf(5), firewalld.icmptype(5), firewalld.service(5), firewalld.zone(5).
