    systeminstall: apt backend is installing the wrong packages
    
    It thinks binutils provides /usr/bin/c++ because that's the first result
    from 'apt-file search', since binutils provides /usr/bin/c++filt. So
    turn off pattern matching at the start and end of the string. We only
    want exact matches.
    
    It still can't install /usr/bin/c++, but that's a much less serious
    problem as we can just tell people to install it.
