They all should be doing prelink operations.  The operation SHOULD be
generically implemented as part of the image-prelink class, which is where I
would have expected that copy to exist.

If any of the package types of specifically doing something, that sounds
broken...  but the generic ones (last I looked) said to copy in the config file
[if it didn't exist], run prelink, remove the file [if it wasn't there to start
with].
