Looking again at the wiki page re splitting dumps, I have created a new 
dumptype:

define dumptype user-tar-span {
  root-tar
  tape_splitsize 400Mb
  comment "tape-spanning user partitions dumped with tar"
}

The wiki then goes on to say

Now, in your disklist file, just invoke that dumptype:

nutdumpling /export/home/building/amanda/dumpdata user-tar-span

This format doesn't make any sense in terms of my disklist, which for this DLE 
reads

borg    /home {
        program "GNUTAR"
        compress CLIENT BEST
        index yes
        exclude list "amanda.exclude"
        } 1

What would be the syntax needed to use user-tar-span here?  Sorry of this 
sounds naive but I'm still missing some basic concepts :-)
