There are some Q&A about updating /etc/fstab but they are all for much older versions of MacOs.
/etc/fstabin fact still supported?
A pointer to what options are supported in
High Sierraand a command line

/etc/fstab were moved away then the volume mounted again so clearly it is the offender. Can it be fixed?
