Just installed chef freshly, however razor gives a depencency error. OS = CentOS 6.4, with latest default yum updates. It would seem to dislike the latest yum cookbook, which is version 3.0.0

You might be able to resolve this issue with:
1-) Removing cookbook versions that depend on deleted cookbooks.
2-) Removing unused cookbook versions.
3-) Pinning exact cookbook versions using environments.

When applying the razor role to an ubuntu 12.04 node, encountered the error here: https://gist.github.com/bunchc/7895910

seems its having trouble finding or creating the ipxe.iso file.

Per this thread:
https://groups.google.com/forum/#!topic/puppet-razor/aYg0o-1vsV4

I'd like to propose we change the default repo to something hosted elsewhere until such a time as the new version is released / functional.
