It's very nice to see this technology revived.

Is the information at:
http://pramfs.sourceforge.net/
and
http://pramfs.sourceforge.net/pramfs-spec.html
still valid - particularly the latter?

It would be very nice to see this get mainlined. I believe that
one of the main uses for this is to store crash information
over a reboot so the next kernel (not in crashing state) can have
a better chance of dealing with it. As such, I think
it's important to keep the code paths for Pramfs short, synchronous,
and unentangled with other kernel systems (block IO, page cache, etc.).
