Thanks for the suggestion! And following on from that, we would do "mount -o remount,ro /path/to/realroot" during shutdown where /path/to/realroot is the bind mount that we created based on your advice? Unfortunately, that approach doesn't solve the problem. If you remount a bind-mount as read only then the "real" underlying mount is unaffected. See the code flow in do_remount() : if (flags & MS_BIND) err = change_mount_flags(path->mnt, flags); else err = do_remount_sb(sb, flags, data, 0); Any other ideas?
