OK, excuse my ignorance here. If I return RPMRC_FAIL for these, will it fail 
the installation of the package, or just spew warnings? I didn't want to get 
into a state where I had to check the file system for each file, before I 
enabled verity on the file.

Do you prefer I return RPMRC_OK if it's not supported, but RPMRC_FAIL if it 
actually fails? I'll have to have another look at all the return values to make 
sure I have them covered correctly.
