Sieht gut aus. Nun die fstab aus deinem installierten System zeigen, also /mnt/etc/fstab nach dem Einbinden von dem ganzen Kram.

/etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.
