commit 093c2cfe3b1ae6081f12927ae7906d90d6623534
Author: Tobias Hunger <tobias.hunger at gmail.com>

    fstab-generator: don't accept missing root=, but accept root=none
    
    And other non-device entries (like fstab does).
    
    Mount whatever the user asked to be mounted on / on the kernel
    command line. Do less sanity check and do *not* bail out
    when the mount device looks strange or does not exist.
    
    This basically makes the changes for deviceless filesystems
    from yesterday unnecessary and is in line with what we do for
    filesystems set up in fstab.
    
    Remove some code that is now dead (reverting fb02a2775a65 and
    b0438462).
    
    [tomegun:
      - change patch title/description a bit.
      - don't touch the /usr logic, that would be a separate change and
        we don't currently have a convincing use-case for that.
      - don't bail out on /sys ro. This only makes sense in containers,
        where we would not be doing this anyway. If there is a use-case
        we could consider that as a separate patch.]
