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). -- regards Thomas
