You need to add the correct UUID as is shown by listing then using
$ lsblk -o PATH,LABEL,NAME,UUID
I have been using fstab for years just as everyone else. Then I decided to learn how to use systemd - and I came to the conclusion - waoo - this is much easier.
A second thing I learned is that for a very basic system - you don’t need fstab - yes - you don’t. If you ensure the correct partition type UUID the system will boot without fstab.
I wrote a guide for the now archived forum. The guide has been ported and can be read following below link
