Centos – Kickstart fails to set up multiple bonded interfaces

I’m having some trouble setting up bonded interfaces in a CentOS 6.5 kickstart script. I have 8 physical network interfaces, which want to be configured in pairs as 4 bonded network interfaces.

My network settings are as below:

network --device=bond0 --noipv6 --bootproto=static --onboot=yes --ip=172.123.1.22 --netmask=255.255.255.0 --bondslaves=eth0,eth1 --bondopts=mode=active-backup,primary=eth0,miimon=80,updelay=60000

network --device=bond1 --noipv6 --bootproto=static --onboot=yes --ip=172.123.2.22 --netmask=255.255.255.0 --bondslaves=eth2,eth3 --bondopts=mode=active-backup,primary=eth2,miimon=80,updelay=60000

network --device=bond2 --noipv6 --bootproto=static --onboot=yes --ip=172.123.3.22 --netmask=255.255.255.0 --bondslaves=eth4,eth5 --bondopts=mode=active-backup,primary=eth4,miimon=80,updelay=60000

network --device=bond3 --noipv6 --bootproto=static --onboot=yes --ip=172.123.4.22 --netmask=255.255.255.0 --bondslaves=eth6,eth7 --bondopts=mode=active-backup,primary=eth6,miimon=80,updelay=60000

network --device=eth0 --noipv6 --nodns --bootproto=static --onboot=yes

network --device=eth1 --noipv6 --nodns --bootproto=static --onboot=yes

network --device=eth2 --noipv6 --nodns --bootproto=static --onboot=yes

network --device=eth3 --noipv6 --nodns --bootproto=static --onboot=yes

network --device=eth4 --noipv6 --nodns --bootproto=static --onboot=yes

network --device=eth5 --noipv6 --nodns --bootproto=static --onboot=yes

network --device=eth6 --noipv6 --nodns --bootproto=static --onboot=yes

network --device=eth7 --noipv6 --nodns --bootproto=static --onboot=yes

My problem is this: bond0 is set up correctly, but bond1, bond2 and bond3 are not set up.

I have seen a number of messageboard posts on similar topics, and the resolution always seems to be to put in a custom bash script for the purpose of setting up the bonded interfaces. However, I don’t think I believe that this is the only way to do it. Why would there be a mechanism in the kickstart file for setting up bonded interfaces if it doesn’t work properly?
