Comments at the bottom. First the src.rpms in Rawhide, which are completely obsolete because all built binary rpms are obsoleted. Those should get retired properly:
All builds obsoleted: --------------------- chktex classads detex drupal6-drush ff-utils gpp4 ibus-table-array30 jadetex jaxen-bootstrap joystick kdirstat latexdiff mate-conf mate-conf-editor metapost-metauml nss-myhostname pdfbook pdfjam ps2eps python-cryptsetup python-lvm python-quantumclient rdate seahorse-plugins tetex-IEEEtran xmltex zeitgeist-datahub
Only obsolete subpackage(s): ---------------------------- lzma ['lzma'] 2 left openswan ['openswan'] 1 left ruby-gnome2 ['ruby-gtksourceview2', 'ruby-gtksourceview2-devel'] 24 left yum-utils ['yum-plugin-security'] 27 left
In this second list, the obsolete binary rpm names are in brackets, and the number of remaining subpackage rpms is appended.
# repoquery --whatobsoletes lzma xz-lzma-compat-0:5.1.2-4alpha.fc19.x86_64
The lzma-libs and lzma-devel subpackages are not obsoleted, just the base package is. Package "scotch" is the only one that depends on lzma-libs.
For openswan, the openswan-doc subpackage is not obsoleted, just the base package is.
# repoquery --whatobsoletes openswan libreswan-0:3.3-1.fc19.x86_64
That's strange, because openswan is a dead.package. :-/
