Created attachment 468609 [details] Don't add --setopt=tsflags=nocontexts to all commands I already posted this on buildsys-list but it seems to have been missed. The SELinux plugin adds a hook that adds a "--setopt=tsflags=nocontexts" option to every command routed through mock.util.do. This doesn't just include "yum" commands, as can be seen for instance if a build fails in the "setup" phase, where mock tries to unmount all mounted filesystems with a umount command with the bogus option added to each invocation. You can see this for yourself if you try building a package that pulls in a build requirement that uses file capabilities and have the tmpfs plugin enabled; rpm/cpio cannot apply the capability on tmpfs and so the build bails out. I use "spamass-milter" in Rawhide as a nice, small package that demonstrates this effect. WARNING: Command failed.

The attached patch makes the plugin only apply the extra option when the command being run is yum. Works for me, though it uses "startswith" and so won't work on python 2.4. I'm sure a native python speaker could write it in a more portable way.
Thanks Paul, yeah I missed it on buildsys-list. I've pulled this in and will add it to mock-1.1.8.
I can confirm both the problem and the patch fix in a current up-to-date F14 installation withmock-1.1.7-1.fc14.noarch.
The fix is included in mock 1.1.8, which you can grab here: http://kojipkgs.fedoraproject.org/packages/mock/1.1.8/ There are a bunch of other fixes in there too. I've been using it for a week now without problems.
Any chance mock 1.1.8 can get pushed? It seems to work fine.
