[Ltib] Preferred way to generate a R/W image

[Neven Boric]

Hi,

What would you say is the preferred way to have a R/W image using LTIB?

I'm familiar with openWRT, which uses both a squashfs (ro) and a jffs2 
(rw) partition, then uses mini_fo to present both as one large rw 
filesystem. The squashfs contains the base firmware. Whatever files the 
user mofifies (configuration files, package upgrades) are written to the 
jffs2 partition. mini_fo makes sure the user always sees the newest 
version of a file.

Is there a similar scheme implemented in LTIB, or would I have to 
implement it myself?

Some further details if you're interested:
