Rigth, for more complicated configurations this is the way to go.

But we don't have a static configuration. We use something like this:

=> setenv bootargs $(bootargs) ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname):$(netdev):off

Right,  we  use  PPCBoot  as  firmware  and  get  all  the  "dynamic"
configuration   by  PPCBoot's  feature  to  define,  store,  and  use
variables.

... not when we can pass all the necessary parameters on the  command
line (or in bi_recs :-)
