    etcupdate: Preserve permissions when installing a resolved file.
    
    Similar to the change in 1a04446f088c79cc2cf85fd86e60ebcc228d3075, use
    cat to overwrite the contents of the existing file rather than cp so
    that metadata of the existing file such as permissions and ownership
    is preserved.
