${AUTODISTDIR} was found in /proc/mounts. If you have anything
mounted under ${AUTODISTDIR} using --bind, you should press ^C now and
unmount it, since ${AUTODISTDIR} is cleaned out by this script. (This
is probably the case if you have run this script and interrupted it
before it completed.) Note that this is just a safety precaution, and
if ${AUTODISTDIR} is a separate partition in itself, you might be OK.
Press ENTER to continue.
