commit fde513554cd7531ab2a6ee30b3a1e392e17a6084

    Conditional creation of /etc/fstab.
    
    * This is one of a series of interventions that means to be gentle to
    debian-live builders and to persistence users; the rationale is that
    if a file is present on the rootfs it does not need to be overwritten
    from scratch since its presence means either a live-helper
    configuration at build time or a persistent/snapshot at run time.
