Something I played with a while ago might allow that.
I found that a single disklist entry could "include"
mountpoints under the top-level directory.  It would
be something like this:

   butch.jgcomp.com  wholesystem  / {
        <other disklist options>
        program GNUTAR
        include append /usr
        include append /export
        include append /var
        include append /var/spool/mail
        include append .
   }

I never tried the last entry, something to include the root
file system.  But it would be needed to get the entire system.
I only explored whether multiple file systems could get into
a single DLE.

One thing I was considering it for was backing up a project
that might have pieces spread over several file systems.
So you might do something like:

   host project / {
        ...
        include append /opt/project
        include append /usr/local/project
        include append /etc/opt/project
        include append /home/jon/Projects/projects/reports
   }

Sorry if some of the syntax is not accurate, I don't have
a working example available at this time.
