sadly, i need the ability to update arbitrary files anywhere in the root filesystem on demand (but only on occasion). updating application-specific stuff is easy as all that is stored in a totally separate flash chip, formatted as a single JFFS2 filesystem, so that part is easy. it's the fundamental root filesystem contents that are the issue here, but i think wolfgang has given me what i need to handle this. rday ** Sent via the linuxppc-embedded mail list.
