Add design doc

Please check for:

• Grammar, clarity, etc
• That I accurately recorded the discussion
• Formatting seems good

I only did the partitioning issue. We can add summaries of other closed issues in more PRs.

I envision that when we want to close out an issue, we PR this doc with a summary. Once we agree the PR is good and accurately encapsulates the discussion, we merge the PR and close the issue.

As the doc grows we may want to break it out into multiple docs in a directory, but that can come later.

Finally, I'd prefer to keep this doc about design of FCOS itself and not about the process around it. We can have a seperate doc for that (the README does a great job right now) if we want.

sorry, bay be this is not proper place, do you think about steps that needs to be done to move from old atomic to fcos ? Or process is simple - reformat/reinstall ? =)

[ajeddeloh]

Not really the proper place, but I'll answer anyway =)
See https://discussion.fedoraproject.org/t/launch-faq-how-do-i-migrate-from-fedora-atomic-host-to-fedora-coreos/51

tl;dr: You'll want to reprovision. For one, FCOS will use Ignition instead of cloudinit for one. Rebasing might work but that's very much in the "proceed at your own risk" and completely unsupported.

It's still to early to tell what exactly will change, but reprovisioning will be your best bet regardless.

Thanks!

Not sure if it's just a bug in the Rich Diff but it doesn't seem to be linking properly to #18
