Following change is required to run mock in OpenVZ: sed -i 's/|mockbuild.util.CLONE_NEWUTS//g' /usr/sbin/mock As it doesn't seem to be critical this flag can probably be moved to extended_unshare_flags. thank you very much. that worked great as a workaround. Been a while sicne I used actual sed, was before GNU added the -i flag. was actually one of the big pushes for me to move to perl years ago for my admin editing (perl's -i flag) FYI, If I move the flag to the extended_unshare_flags, it works as well. a diff for that change: --- /tmp/mock 2013-01-17 09:52:07.000000000 -0800 +++ /usr/sbin/mock 2013-01-17 11:47:59.000000000 -0800 @@ -760,8 +760,8 @@ os.environ["HOME"] = chroot.homedir # New namespace starting from here - base_unshare_flags = mockbuild.util.CLONE_NEWNS|mockbuild.util.CLONE_NEWUTS - extended_unshare_flags = base_unshare_flags|mockbuild.util.CLONE_NEWPID|mockbuild.util.CLONE_NEWIPC + base_unshare_flags = mockbuild.util.CLONE_NEWNS + extended_unshare_flags = base_unshare_flags|mockbuild.util.CLONE_NEWPID|mockbuild.util.CLONE_NEWIPC|mockbuild.util.CLONE_NEWUTS try: mockbuild.util.unshare(extended_unshare_flags) except mockbuild.exception.UnshareFailed, e: what kernel were you running on that failed with CLONE_NEWUTS? 2.6.32-042stab065.3 (openvz) Well that's odd. CLONE_NEWUTS was added back in 2006, three years before 2.6.32 was released. Does your kernel not have CONFIG_UTS_NS turned on? I can move CLONE_NEWUTS to the extended flags but it seems odd that your kernel doesn't have it turned on. OpenVZ: 2.6.32-042stab068.8 From reading the docs on CLONE_NEWUTS, it sounds like it is what a container itself would use and since I am already running mock inside of an openvz container would that still be legal to do?

move CLONE_NEWUTS from base flags to extended flags
I've got this patch in my current tree but I haven't tried it on older kernels yet. Please verify that it fixes your issues and it will go into the next mock release.

Probably not. I think the patch I just posted will do the trick (It's essentially what Richard did in #c4). Yup, that looks the same as what I did in comment #2. mock-1.1.29-1.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/mock-1.1.29-1.fc17 mock-1.1.29-1.el6 has been submitted as an update for Fedora EPEL 6. https://admin.fedoraproject.org/updates/mock-1.1.29-1.el6 mock-1.1.29-1.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/mock-1.1.29-1.fc18 Package mock-1.1.29-1.el6: * should fix your issue, * was pushed to the Fedora EPEL 6 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=epel-testing mock-1.1.29-1.el6' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-EPEL-2013-0476/mock-1.1.29-1.el6 then log in and leave karma (feedback). mock-1.1.29-1.fc18 has been pushed to the Fedora 18 stable repository.
