+       * duplicity: duplicity now uses sftp, which does not support all scp
+         command line options; you thus have to convert the sshoptions setting
+         in your *.dup configuration files, to sftp-compatible syntax; for
+         example, you can replace:
+           sshoptions = -i /root/.ssh/id_dsa_duplicity
+         with:
+           sshoptions = -o IdentityFile=/root/.ssh/id_dsa_duplicity
