Cool, although we (Red Hat) are already making the first steps towards this
as part of our initiative to implement the EL/IX level 1 API
( http://sourceware.cygnus.com/elix ) in eCos. This will very much be an open
development, and once we get a few more details thrashed out, we would
encourage you to help out in any places you feel like. There'll be more of
this shortly!

That's exactly what the group here thinks too. In saying that, a RAM-based
FS or something would be a useful starting place as a proof of concept, and
for testing, if nothing else. But with the implementation of "full" CDL, we
now have the functionality available from the configuration system to
support proper plug-in filesystems cleanly.

More shortly...
