    Yes. The proc file-system can be mounted multably. You can check this
    out if you have a ftp server installed. Presume it's home directory
    is /home/ftp. As root do:

    cd /home/ftp
    mkdir proc
    mount proc proc -t proc

    Now execute anonymous ftp. You can `chdir` to what now looks like `/proc`
    in the chrooted environment and get the directory.

    I was able to download `get` cpuinfo even though the ftp message
    said it was 0 bytes. The correct size (on my system) of 722 bytes
    was received okay.


    Cheers,
