Off the top of my head, i can tell you that both lsof and fuser do not show any open files in /ro. I have previously checked this. I will collect the rest of the the information and get back to you.

OK, then let's proceed next step. - run "lsof" after "rsync"  find the file which makes your /ro busy. - after "remount,rw" run "fgrep -w /ro /proc/mounts"  confirm that all /ro entries are remounted as RW. - split the updating files into several groups. for example,  rsync updating/etc /ro  rsync updating/lib /ro  rsync updating/usr /ro     :::  and after for each rsync, try "remount,ro". repeating this step with  narrowing down the updating file, we can find the file which makes  your /ro busy.
