Earlier in this thread I asked about "initfs". Well I finally found a definition here:

http://maemo.org/maemo_release_docum...1.x/node3.html

initfs
Initial file system used as the root file system during Linux kernel boot e.g. for hardware initialization (contains kernel modules and utilities for initializing them). Mounted after boot to /mnt/initfs.

There are some other good definitions there for folks like me who are not acquainted with the jargon used in these forums. This might be a nice addition to the Wiki.
