Hi Kyle

We have had some success running diskless arm32 systems on some of our
products. We based our efforts on /usr/src/distrib/arm32/ramdisk. This
generates a crunched binary of a ffs filesystem, that is inserted into space
reserved for it in the kernel (see the "mdsetimage" manpage). At boot time,
the kernel fetches this filesystem out of itself, and mounts it in RAM. This
is a read only filesystem, and what we have done is written little utilities
that read and write different portions of flash to store the files that need

Let me know if this is the kind of thing you are looking for...
