the check assumes, that if there is something in /dev/pts/*, then it has
to be unmounted. but there is always something in /dev/pts/*, regardless
if it is mounted, udev is running, or plain devices are used. therefore,
any check for existence of /dev/pts/* is insufficient.

(probably, it is sufficient on etch, but it's not on sid.)
