I would certainly like to get that GLEP series completed and out there.

There are still two GLEPs in the series that have not yet made it to
draft status:
http://sources.gentoo.org/viewcvs.py/gentoo/users/robbat2/tree-signing-gleps/02-developer-process-security
http://sources.gentoo.org/viewcvs.py/gentoo/users/robbat2/tree-signing-gleps/03-gnupg-policies-and-handling

However the main content of GLEPS 58-61 IS ready for the council to
approve, and are NOT blocking on the above two items.

As such, I would like to present GLEPS 58,59,60,61 for final review, and
for the council to vote on their approval during the January meeting.

I'm going to summarize them here:
GLEP58: Security of distribution ... MetaManifest 
-------------------------------------------------
- covers all Manifests with a infra-generated parent Manifest.
- required for end-to-end validation.
- prevents certain package manager attacks.
- NO day-to-day developer actions required.

GLEP59: Manifest2 hash policies and security implications 
---------------------------------------------------------
- Add SHA512 to all Manifest files.
- Schedule removal of SHA1, MD5, RMD160 for 6-18 months after SHA512
  addition.
- Be prepared to add the NIST hash contest candidates/winner.

GLEP60: Manifest2 filetypes
---------------------------
(Has one TODO that needs clarification).
- Breaks down the Manifest2 filetypes into INFOrmational and CRITical.
- If the package manager is being strict, then INFO filetypes are
  treated as CRIT filetypes.
- INFO filetypes merely cause a warning on absence.
- CRIT filetypes may trigger a delayed OR immediate failure of absence.

GLEP61: Manifest2 compression
-----------------------------
- Disk space optimization for MetaManifest from GLEP58.

There is a prototype of the MetaManifest code here:
http://sources.gentoo.org/viewcvs.py/gentoo/users/robbat2/tree-signing-gleps/prototype/
It worked on Portage 2 years ago, but I haven't run it since then.
