+
+    sendRecvSnapshots - don't cut dstDataSet in-place
+
+    The current code in sendRecvSnapshots splits the dstDataSet var
+    early on in the execution chain to provide logging output and the
+    remote variable contents. This removes the remote information from
+    dstDataSet which is then passed to listSnapshots without the
+    remote data and the attempt to list the last snapshot occurs on the
+    local host, not over SSH on the remote target.
+
+    Address the issue by creating a dstDataSetPath variable to hold the
+    stripped target path while retaining the original dstDataSet with
+    the remote information attached for lastAndCommonSnapshots to use
+    in listSnapshots.

+
+    It checks f the `$dstDataSet` exists, if not,

+On Ubuntu / Debian with:

+On Solaris you may need the c compiler from Solaris Studio and gnu-make
