I managed to get a read only root partition following the tutorial on this page.Just to summarize, it uses aufs to create a virtual layer over the real root partition, mounted in read only.Now, the only problem I found is that the USB automount does not work. The mount directory (i.e. /media/user/VOLUME) is invalid. I think this is because the media folder (which resides on root) is read only.I think that the possible solutions can be to either mount the media folder (and so the mount points created in it) in a tmpfs, or to move the media folder on another partition with RW rights.What is the best approach? And how can I achieve that?The OS is Debian 8.6.0, if needed
