Me too. That's why I called your idea nicer :)

I was thinking about some simple solution. I think it would be enough
to create extroot config (for this specific device) right after
formatting JFFS2. Formatting is handled by /etc/init.d/done
(START=95). So I could add script with START=96 that will preapre
extroot and add fstab config entry.

Does it sound sane & clean enough to you?

However: is there some way to tell OpenWrt to re-scan fstab other than "reboot"?
