Which part in that description do you mean? I only find:

> Note that entries for /, /usr/bin, and /usr/lib are never generated.

How can I check wether the files are written to /tmp? In one directory I 
got the error

> sed: preserving permissions for `./sedBHiGtF': Permission denied

which seems to indicate, that the file is not moved to /tmp, right?

Any further ideas? Can somebody reproduce this, or the opposite?

Cheers,
Jan
