-I could mount both partitions correctly after adding the required commands in an init.d script . If the former is not supported by your phone - there are alternatives magisk module ( x-posed is yet another option ) and magisk settings should not be at isolated namespace . For the mount to be propagated & su -mm ( Mount master ) ought to be used
