loading the kernel and root FS separately from flash?

Hi!
We have the same 'problem' if we startet with linux.
I think the point is:
What do you want to update?
In most cases only project related files like configuration or the application itself has to be updated, but not the whole distribution. So look what do you think that is necessayr to update and which files are not.
We use a compressed filesystem without the possibilty to update it (easily). Then we mount a jffs2 partition where the project related files are stored. (In detail: a standard project directory is also stored in the compressed filesystem, and if the hardware boots the first time, the flashdisk will be formated and the standard application copied. So from this point on it could be handled in our system as usual, and also newer application could be stored, wihout the need to update everything)

I hope you could see now clear .-)
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.
