Created attachment 158932 [details] Proposed patch
While this might be a good idea, I think it is something that should be done upstream instead of maintaining a big patch in the Fedora package. There's a ccache mailing list, could you send this there? See http://ccache.samba.org/
I try to send this info to the list w/o subscription. Anyway I've quickly review the maillist archive and I consider the author does not response in it. And I think is not a problem to provide Fedora package with a couple of the patches.
Well, it is a backwards incompatible change even within Fedora, and also incompatible with non-patched (non-Fedora) ccache implementations which may be a problem with shared/networked cache dirs. The Fedora package maintainer's job (myself at the moment) is to cope with the added maintenance burden and has to answer for the introduced incompatibilities. Before upstream indicates support for the idea or includes the patch, I don't think it's the right thing to do that. If the upstream maintainer does not respond to list posts, maybe sending the message directly to him would work better.
