And I have got it working too, butnot quite to my satisfaction.  I will
have to experiment a little more.  But I it does not appear to be a
reiserfs problem.

The following fstab entry works on topoi
/dev/hdc1       /reiseroffsite  reiserfs  defaults    1    2

The following one does not:
/dev/hdc1       /reiseroffsite  reiserfs  noauto,user 0   0

So it has to do with the context of the mount.  Anyway, having it
automatically mounted at boot is not acceptable in the long term
because it is a dismountable volume, and, in fact, most of the time
it sits on a shelf serving as a backup.

debian on topoi,

hendrik@topoi:~$ uname -r
2.4.16-586
hendrik@topoi:~$ 

Mandrake 9.0 on lovesong

[hendrik@lovesong hendrik]$ uname -r
2.4.18-6mdk
[hendrik@lovesong hendrik]$

Experiment suggests it is something *like* that.  Is there some way
of getting it mounted at boot if it is present but ignored if it is
not?  The drive is dismountable, but not hot-pluggable.  I have to
turn the machine off whenever I insert or remove it.  Last time I
had a nonexistent partition mounted at boot it went into some
emergency mode and refused to finish booting until I fixed
to problem.

But even so, there ought to be a way to export even hot-ploggable drives.
