Actually, let me begin again.  

We actually this working on amanda 2.4.1 (I think).  The source code for
amanda-client had to be patched to collect the correct estimate, AND you
had to replace /sbin/dump with the perl script(s), and everything
worked.  When we went to 2.4.2 it broke and we didn't get around to
fixing it.  Now we have a new, larger, filer and the project is back
on.  I've tried letting amanda back up via nfs, but it almost always
fails at some point, the error we get in the sendsize debug is "/bin/tar
cannot create directory"  (or something like that).

You have to create "devices" for the filer in /dev so amanda thinks the
filer is itself, not another host.  

my disklist looks like this:

sherman.cs.unm.edu      /dev/poptart/etc        dump

sherman is my amanda server, poptart is my NetApp.  My entries in /dev/
are:

sherman:/dev# ls -l poptart
total 0
crw-r--r--    1 root     root       1,   3 Jun 12 10:31 etc
crw-r--r--    1 root     root       1,   3 Jun 12 11:43 staff

If I run dump by hand:

/sbin/dump 0usf x - /dev/poptart/etc > somefile

it works fine.

Running it from amanda fails.

When you say "modified dump" do you mean the perl scripts and
setuidump.c?
