I think I'm a bit confused with all the options in the documentation so I was hoping I could get a little info from the list
I've got a system where I mount the root filesystem read-only and overlay a tmpfs on it. I do something like the following in my initrd mount -o move / /root/ro mount -t tmpfs tmpfs /root/rw mount -t aufs -o "br:/root/rw:/root/ro" none / This works great since on these systems I have to worry about users just shutting them off at a whim. When I need to change something on the RO filesystem I can remount it with mount -o remount,udba=inotify / mount -o remount,rw /root/ro and then change it back with mount -o remount,ro /root/ro mount -o remount,udba=reval / this all works great. What I would like to do, though, is take an additional jffs2 partition I have and mount it as something like /etc/preferences where changes to that directory will bypass the root filesystem and the tmpfs and only get written to the jffs2 partition. How can I do this without causing problems with overlays? Also is it possible to do it after the other steps? It would be nice to do the steps above and then later do the /etc/preferences mount if I can detect that it exists.
