    Question 1:
    Has anyone used rvdump with ssh as the transport?

    It seems that rvdump does not use /usr/bin/rsh as I have
    replaced this with a wrapper script to invoke ssh with the
    desired arguments. Here is what my (crude, really dumb)
    wrapper script does:

    #!/bin/sh

    if [ ! -z "$RSH_CMD" ]
    then
        COMMAND="$RSH_CMD"
    else
        COMMAND=/usr/bin/rsh-dist
    fi

    exec $COMMAND $*

    And then execute rdump as so:

      RSH_CMD="ssh -C -i /path/to/key -l NOTROOT" \
        /sbin/rvdump -0 -f remotehost:/dev/st0 /

    But rvdump does not seem to be executing /usr/bin/rsh (ie.
    my wrapper).

    Of course, I could do:

      /sbin/rvdump -0 -f - / | ssh $SSH_ARGS dd of=/dev/st0

    Or some variation thereof. The reason I hope to use
    rmt is to be prompted for tape changing. So I guess
    that is question #2:

    Does rvdump detect end-of-tape and eject/prompt
    for next tape? In my case the remote host with
    the tape drive is a linux system.

    Thanks!
