    base-files: /etc/sysctl.conf: clarity in comment
    
    Make it clear to users that they should not place a custom file
    in /etc/sysctl.d/ for their values and expect it to survive a
    reimage.
    
    This change is needed since these directories (/etc/foo.d/) are
    generally where such files are placed on other distros.
