Just adding here. Personally I went to a 2 stage load for my
flash based routers. When running *much* larger images than the LRP
(8MB to 64MB) uses things got fun, as the double load (load initrd
into memory, then copy/convert to ramdisk, then clear first initrd
copy) blew up due to a lack of memory.
The solution was a micro initrd image that does all the
creation/setup on /dev/ram1 straight from flash, then switch to
/dev/ram1 for root.
Given the move of the latest LRP stuff twards larger images
(not a mainly floppy based system) this might me a good way to kill 2
birds. If done right the on disk footprint is approx the same as your
current loading system, but allows loading *much* larger images
within the current kernel functionality.
