The diskless NFS root file system is simply used for convenience and
to reduce application development time. You can put a root file
system on anything that will hold the bits.

Yes, there are many systems using a variety of solutions to Flash rom
root file systems. You have to consider your own application
requirements to choose what is appropriate for you. You can use
a compressed initrd stored in flash rom, which is uncompressed into
a ram disk. Another popular alternative is PCMCIA flash disks,
compact flash or Smart Media cards. You can put a file system on them,
partition them, and compress some or all of the data. Least favorite
on my list, but used by some people, is soldered on-board flash rom
parts. Wear leveling and dynamic allocation are complex algorithms,
and above a rather small size compact flash cards are more cost effective.
All of this is supported by standard Linux distributions, and the boot
code in the PPC port handles it well.
