I have quite a few packages in my two main projects now (around 120) and the biggest part are kmp-packages.

Some of them, especially for openSUSE_Factory have become obsolete, I started building them when Factory used kernel 2.6.29, now we are at kernel 2.6.31 and a quite a few drivers were merged into mainline during that time.

So what I always did (when a driver became obsolete) was:

a) Wiped the binaries from the repository in my OBS project (osc wipebinaries *foo* *bar* *whatever*)

b) disabled building of $PACKAGE for Factory (while still leaving build enabled for other versions, of course)

So my OBS project itself looks "clean" now, however, the respective packages are _still_ available on the download servers.

BTW:

No, this was not done during the power outage, all of those packages were cleared and disabled weeks/months ago, which you can also see by their last publishing date.

Let me give you an example:

NONE of these kmp-packages is still needed and none will be installable on a recent version of factory, they are just wasting space on the server.

The last point is of no big concern to me, but if $USER tries to install one of those packages, (s)he will of course get error messages and probably start annoying me with useless "Thingy no workee" mails.

And even if I would bother to answer (which in most cases I won't at least on Factory, because I think users installing factory are supposed to know what they are doing or at least understand the error message), I could only tell them, that those packages should not be available any longer and I have no way to handle that.

The only way I found out to remove packages in a repo on the download servers is either to delete the package completely (which is no option as most of those packages are also being built for 11.1, 11.0 and sometimes even for 10.3) or to delete the repo openSUSE_Factory completely (which obviously is also not an option as it will delete the about 50 other packages which still _should_ be available for Factory, too).

Is there anything I have missed in the documentation or more directly is there a way to get rid of them also _on_ the download servers?
