#5 find correct repository for 'system packages'

[Silver]

Sometimes package's repository shows up as '(System Packages)'. It happens always when a repository is removed, but also when a package's currently installed version is no longer available in its repository.
Finding the correct repository for such package is possible with 'rpm -qi' or 'zypper info' commands. Or maybe use libzypp via Ruby bindings?
Would it make sense to use either of those?
