this seems enough to make the problem disappear, without mounting the
file system Harald suggested. (I prefer not to do that because
sometimes I have to do this on boxes on which I have no root password
and/or control on how to mount file systems)

Thanks a lot to Harald and Gordon!!!

my understanding is that -c completely avoids all these headaches, but
is not used normally ONLY because it would be much slower.  if it
isn't so, please let me know, otherwise no need to answer.
