    Don't change directory while running init-runonce

    Currently init-runonce script changes directory to the
    script's base directory (/usr/...) before doing anything else.
    This unnecessarily _forces_ a non-root user to use sudo for
    running this script thereby raising privileges for code which
    doesn't want it. Also downloading temporary stuff in places like
    /usr... seems not a good choice.

    Hence deleting the said code part and letting the deployer work
    comfortably from any directory.

    Made documentation changes accordingly.
