The root of your system. Usually '/', unless you use --root.

Yast is too confuising ;). Try zypper or some of the tests/examples in the 
libzypp git.

See the attached example. Slightly modified from
git://gitorious.org/opensuse/libzypp-bindings.git
(examples/python).

Beware, the examples are pretty outdated but at least list_resolvables works. 
(patches/suggestions are wellcome ;) I added an onSystemByUser call as you 
asked for some 'p.installedBySolver' in the previous mail. 

Since libzypp-7.5.0:
+       /** Whether this is known to be installed on behalf of a user request.
+        * \note This is a hint guessed by evaluating an available install 
history.
+        * Returns \c false for non-system (uninstalled) solvables, or if no 
history
+        * is available.
+        */
+       bool onSystemByUser() const;
