Sorry. (Somehow I don't seem to be receiving this mailing list anymore, have to check.)

I don't see how fstab should be related to these path problems. Maybe your comment
refers to the above? (Maybe I should have split the problems into different issues anyway...)
Actually, looking again, I see with 1.5 (and no fstab which did not reappear when I
reverted), there is this kind of double mount or re-mount which effectively maps /usr/bin
to /bin. I had wondered about the purpose of this before. Is it good to use this trick
to fix situations where programs (like rsh) refer to /usr/bin to get them find their
sub-programs in /bin? Wouldn't it be better to install those applications (tbl, nroff, ...)
in /usr/bin in the first place (I see that's where they are on my Linux)?

Just to answer your question: No, it was a local file. Also I cannot copy an "x." file
from an NFS drive to the local drive (with 1.5). As I said, I cannot reproduce the
situation, I'm very sorry this will probably remain mysterious.
Kind regards,
