Just "ls -s /usr/ftp/userdir /home/userdir" would work, but I have a
better idea.  Assuming the box in question is running a 2.4.x kernel,
you can use "mount --bind /usr/ftp/userdir /home/userdir".  Then there
is no symlink.  Add the following to /etc/fstab so it works on boot:

    /home/userdir    /usr/ftp/userdir    none    bind    0 0

Of course, the *real* answer for the future is to use LVM so that you
can just use e2fsadm to shrink /usr and grow /home.  (Since they are
adjacent partitions, you could do it now without LVM, but it is
*really* painful.)

One other thought...  You'd get a little bit of space back if you
unmounted /home and did "tune2fs -r 0 /dev/sda3" to set the reserved
block count to 0 on that filesystem.
