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. > If you want to build a lean system you have to do it the other way > round: bottom up. 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? ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
