    There is no such thing as a "fair use threshold". That is a legal
    fiction.  There is a principle of de minimums, but that involves
    importance as well as length. It is very easy for a single line of
    code to be critical and fully protectable (there are court cases that
    have hinged on VERY small sections of code).

True in general, but not in the cases of these host machine file.  They are
making declaratory statements about properties of the host machine and are
being done in the only way possible given those properties.  I'd argue they
aren't protectable by copyright *at all*.
