From: Greg Rose <[email protected]> A bug in RHEL 7.2 has been found in which a customer who installed a RHEL 7.2 openvswitch kernel module rpm with a slightly different minor build number than the rnning kernel found that the kernel modules were installed to the wrong directory.
After the installation the new openvswitch kernel modules were installed to: /lib/modules/3.10.0-327.22.2.el7.x86_64/extra/openvswitch But the running kernel was 3.10.0-327.el7.x86_64 and after the installation was complete the kernel modules in the installed directory were not linked to the "weak-updates" directory in the running kernel. So the customer was not able to load the correct kernel modules and a critical bug was encountered. This patch does a post installation sanity check to make sure that the ../extra/openvswitch directory or the ../weak-updates/openvswitch directory at least exist.
