No. But....
using fai-cd you can create different flavours of a boot CD.
A boot CD with just the kernel and the initrd, or a CD including
additionally the nfsroot.
In your case a boot only CD (kernel+initrd) should be fine. Have a
look at the man page dracut.cmdline(7) (which we are using to build
the initrd). This includes already options for bonding:
bond=<bondname>[:<bondslaves>:[:<options>[:<mtu>]]]
Setup bonding device <bondname> on top of <bondslaves>. <bondslaves>
is a comma-separated list of physical (ethernet) interfaces. <options> is a
comma-separated list on bonding options (modinfo bonding for
details) in format compatible with initscripts. If <options> includes
multi-valued
arp_ip_target option, then its values should be separated by
semicolon. if the mtu is specified, it will be set on the bond master. Bond
without
parameters assumes bond=bond0:eth0,eth1:mode=balance-rr
Also read man fai-cd(8).
