With unionfs, you don't (and shouldn't) modify the read-write status of 
the system.  That's why the changes don't make it past a reboot.  If you 
edit a file, the changed file is written to the unionfs partition and 
when seen by the OS, that file is used instead of the file on the image.

(so if /etc/modprobe.conf exists in the image AND 
/oldroot/mnt/asturw/etc/modprobe.conf exists, the latter will be used).
