The network bridge is not configured with the bridge configuration in kickstart without bridge= boot parameter in Red Hat Enterprise Linux 7.2

Issue

• The network bridge is configured in kickstart as below.

network --device=bridge0  --bridgeslaves=eth0  --bootproto=static --ip=192.168.120.1 --netmask=255.255.255.0 --gateway=192.168.120.254  --hostname test1

• The installation with Red Hat Enterprise Linux 7.2 failed, and it entered the emergency shell.
• When bridge=bridge0:eth0 as a boot parameter is given, the problem doesn't happen.
• But, it should work even when the boot parameter is not given.
