After the mirroring there are two /etc/fstab files, one in each place.
The one on the microsd card media needs to be changed as it will be
found and used to mount what it lists for / . After that the /etc/fstab
on what is mounted on / will be used as I understand. (But I normally
keep the two files tracking and so would not see the distinction.)
