You can probably thank DNF for that. It's idea of the right packages is
different from yums.

Remember that this is not livecd-creator, and it was not designed to
give you the same output.

Don't you already have to do that with the new lmc koji code to grab the
output from the run inside mock? I really don't see the need to add yet
this to lmc when your code can easily move the boot.iso to the final
location/name and remove the intermediate directory.

lmc uses lorax to create the iso output, which it why it looks very much
like a boot.iso tree. I want to minimize differences from lorax as much
as possible.

Thanks for doing this, in this case I think it belongs in the new koji
code, not lmc.
