Not true. Once a file is open, it doesn't matter where it is on the
directory tree. The filesystem already has a dev/inode pair for the file,
and it doesn't matter WHERE in the directory tree that pair is. As
evidence, I offer the fact that my ftp logging patches work, and have been
working for quite a while now.

have an open file descriptor, any amount of chroot-ing isn't going to
affect it. --wnl ]]
