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.
