# digest/hashing target

Most of this has spun off with [1], and I haven't heard of anyone
talking about verifying the on-disk filesystem in a while.  My
personal take is on-disk verification doesn't add much over serialized
verification unless you have a local attacker (or unreliable disk),
and you'll need some careful threat modeling if you want to do
anything productive about the local attacker case.  For some more
on-disk verification discussion, see the thread starting with [2].

# distributable-format target

This spun off with [1].

# lifecycle target

I think this is resolved since 7713efc1 (Add lifecycle for containers,
2015-10-22, #231), which was committed on the same day as the ROADMAP
entry (4859f6da, Add initial roadmap, 2015-10-22, #230).

# container-action target

Addressed by 7117ede7 (Expand on the definition of our ops,
2015-10-13, #225), although there has been additional discussion in
a7a366b3 (Remove exec from required runtime functionalities,
2016-04-19, #388) and 0430aaf1 (Split create and start, 2016-04-01,
#384).

# validation and testing targets

Validation is partly covered by cdcabdeb (schema: JSON Schema and
validator for `config.json`, 2016-01-19, #313) and subequent JSON
Schema work.  The remainder of these targets are handled by ocitools
[3].

# printable/compiled-spec target

The bulk of this was addressed by 4ee036fc (*: printable documents,
2015-12-09, #263).  Any remaining polishing of that workflow seems
like a GitHub-issue thing and not a ROADMAP thing.  And publishing
these to opencontainers.org certainly seems like it's outside the
scope of this repository (although I think that such publishing is a
good idea).
