Greetings,

I have a centos 5.7 (2.6.18-274.12.1.el5) server with mock
(mock-1.0.25-1.el5) installed. When initialize epel-6 chroot in centos 5.7
it failed, below are the snippet of error in the terminal output,

I've tried clean and reinitialize the chroot but it failed. Google for this
issue and mailing list only result in failed to build rpm in C5 from C6
(which is opposite of this). Has anyone successfully initialize or build
srpm in C5 mock for C6 or is there a fix for this?

Thank you. /Jason
