A question about openSUSE repositories

I’ve install openSUSE 12.2 and noticed that the following repositories in YAST.

These four are official openSUSE repositories from installation:

http://download.opensuse.org/update/12.2/
http://download.opensuse.org/update/12.2-non-oss/
http://download.opensuse.org/distribution/12.2/repo/oss/
http://download.opensuse.org/distribution/12.2/repo/non-oss/

Packman (an external repository of openSUSE packages) was installed by me for multimedia support:

http://packman.inode.at/suse/openSUSE_12.2/

The following four are installed via 1-click when searching for packages from software.opensuse.org: Search :


http://download.opensuse.org/repositories/Printing/openSUSE_12.2_standard/
http://download.opensuse.org/repositories/X11:/windowmanagers/openSUSE_12.2/
http://download.opensuse.org/repositories/security:/passwordmanagement/openSUSE_12.2/
http://download.opensuse.org/repositories/security/openSUSE_12.2/

Are packages from the above four repositories offically supported by openSUSE ?

If yes, why aren’t these packages included in the default openSUSE repositories?

AFAIK only these are officially supported :


http://download.opensuse.org/update/12.2/
http://download.opensuse.org/update/12.2-non-oss/
http://download.opensuse.org/distribution/12.2/repo/oss/
http://download.opensuse.org/distribution/12.2/repo/non-oss/

Even packman is not officially supported even though everyone uses it.

If I were you, I would disable the last four. You have from them what you need and you never know what is put on them that may interfere with the official ones. When you want to see if newer versions of the software you iinstalled from them is available, enable them one by one and check. But leave them disabled in daily life.
