At first I was going to suggest an extra-verbose or a debug mode on the toolchain to help on this, but I suspect that identifying the block in a useful fashion wouldn't be possible. When resolving the blocks, is there even any reference to the module it comes from? Beyond that, there probably aren't line numbers either, so it couldn't have messages like "block disabled: optional beginning on line 123 from foo.pp." -- Chris PeBenito Tresys Technology, LLC www.tresys.com | oss.tresys.com -- This message was distributed to subscribers of the selinux mailing list.
