from amdump manpage:

   SYNOPSIS
      amdump config [ host [ disk ]* ]*


I'd probably label a new tape and write a shell script to
do things like this:

   make sure your desired tape is loaded
   reset the entry for that tape in tapelist file to whatever is "new"
   run the appropriate amdump command for that DLE

I don't know of a one-time to set "no record".  So I'd make up
a new dumptype for testing that is no record and no index.

Be sure to change dumptypes when done testing.

selinux turned on in FC5?  probably not in rh9.

does something in that have to be activated or configured
for amanda to work?
