[one-ecosystem] VM_DIR and tm_nfs clone disconnected ? Part II

I have made some progress tracking down the root cause of this issue.

In tm_common.sh, function fix_paths significantly alters the image file
source and destination path strings. I would make the changes, but I'd like
to know the intent of the code.

In the tm_commom.sh script below, variables ONE_CONF and ONE_LOCAL_VAR are
setup depending on whether environment variable ONE_LOCATION is configured.
If the location variable is not set, the default system install path is
used. When the location variable is set, the string has either a
"/etc/oned.conf" and a "/var" appended to it.

In my configuration, I would have:
ONE_CONF: /opt/one/etc/oned.conf
ONE_LOCAL_VAR= /opt/one/var

>From tm_common.sh:

if [ -z "$ONE_LOCATION" ]; then
    ONE_CONF=/etc/one/oned.conf
    ONE_LOCAL_VAR=/var/lib/one
else
    ONE_CONF=$ONE_LOCATION/etc/oned.conf
    ONE_LOCAL_VAR=$ONE_LOCATION/var
fi

Below,  function "get_vmdir" sets variable VMDIR to the path. In my case its
"/vm-images"

function get_vmdir
{
    VMDIR=`cat $ONE_CONF | grep ^VM_DIR= | cut -d= -f2`
}


If the VMDIR is set,  function fix_paths attempts to adjust the source and
destination. I'm not sure what they are trying to achieve here,
concatenating the existing path, the VMDIR and local var path or a
substitution ?

function fix_paths
{
    if [ -n "$VMDIR" ]; then
        SRC_PATH=${SRC_PATH/$VMDIR/$ONE_LOCAL_VAR}
        DST_PATH=${DST_PATH/$VMDIR/$ONE_LOCAL_VAR}
    fi
}
