Encourage the use of static device names in fstab

[Romain LE DISEZ]

Using unstable name devices (eg: /dev/sdb) for Swift in /etc/fstab is a risky idea.

The documentation does not encourage the use of stable name devices, and it also shows[1] the use of unstable device names.

The documentation needs to encourage the use of stable device names. Presumably one of:
- label
- uuid
- id
