There is one point that I didn't make clear. We are booting the board
over the wire, and we can afford the cost of 64MB DIMM instead of a 16
MB DIMM. We have a modest amount of flash on the board 2-4MB -- This
is more than enough to hold PPCBoot.
If the board needed to be self contained, then the size of the root
file system would be much smaller. The cost of flash is greater than
a DIMM, so it justifies the additional work in creating a 2-8 MB root
file system.

I would of taken this approach, if my goal was root filesystem that
was less 8 MB.
Open Question:
How have other people have dealt with the creation of a root file
system?
