RHEL 6 and kABI/kmod Packaging

I discovered this perl scriptlet is failing because mock unmounts /dev
in the chroot before it runs the scriptlet.  Perl can't find /dev/null
and blows up. 

Red Hat is building these kABI packages with mock, but I'm unable to get
it to work at this point without patching mock itself.  

Does anyone have any advice for getting these mock builds to work?
