I have now written up a proposal for the mechanics of bootmethod / bootflow for review. Think of it as a newer version of Distro Boot. I'm not sure how to format it for the mailing lists, so please see : [1] VBE doc with minor updates [2] Proposal for the bootmethod/bootflow part of VBE Please let me know if you would like to comment on the source docs [3] and [4].
