   * Rename installed_alternatives() to _installed_alternatives().
   * Add /etc/pki/tls/openssl.cnf to list of default openssl config files,
     search for default ones only if -config is not given.
+  * Use POSIX compliant arguments to tail in mkisofs completion.
+  * Protect various completions from unusual user input by not embedding the
+    input in external command arguments.
