There is still one rpm dep left. See attached hack patch.
We just need to make that kernel check generic and not use the rpm
labelCompare call. For RH/tcmu-runner based distros we do not need a
specific kernel version check plus the distro version check.
tcmu-runner/target_core_user should return an error if something is not
supported if the kernel is not supported.
Ricardo,
For SUSE/target_core_rbd, I think we just need to add a check for if
target_core_rbd is available, right? Maybe we want a backstore specific
callout/check?
