Mine was from a non-LiveCD. The ifcfg files generated look fine:
# Intel Corporation 82557/8/9/0/1 Ethernet Pro 100
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:d0:b7:85:f6:03
ONBOOT=no
DHCP_HOSTNAME=bofh.xelerance.com
# Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet
DEVICE=eth1
BOOTPROTO=static
HWADDR=00:0c:76:bc:9b:d1
IPADDR=193.110.157.17
NETMASK=255.255.255.248
ONBOOT=yes
eth0 has (or had) no link during install.
To be it looked like despite being confgured with BOOTPROTO=static, the
avahi daemon and NetworkManager got started, and one of them started
doing dhcp. The static IP did appear as an additiona IP on the eth1
interface, but since the DHCP was the main address, my public ip address
changed.
ONBOOT=no means that NM won't try to automatically bring it up. That
may be what you're seeing.
