7cacb2e127 Revert "fix(units): Drop automatic daemon-reload"
daemon-reload should be fixed now and the latest CoreOS with locksmith
is causing the etcd unit to get lazy-loaded before all the cloudinit
processes have finished configuring etcd via dropin files. In short,
the luck we were relying on to get by without daemon-reload has
officially run out. Cross your fingers!

This reverts commit 580460ff3f.

26b54534d6 fix(configdrive): Always run after OEM and ec2 metadata.
A workaround for https://github.com/coreos/coreos-cloudinit/issues/86

Longer term cloudinit needs to be fixed to not corrupt the system when
multiple config sources are being used. We've pretty much gotten this
far without this coming up because most configs don't conflict so badly.

# How to Contribute
CoreOS projects are [Apache 2.0 licensed](LICENSE) and accept contributions via
GitHub pull requests. This document outlines some of the conventions on
development workflow, commit message formatting, contact points and other
resources to make it easier to get your contribution accepted.
# Certificate of Origin
By contributing to this project you agree to the Developer Certificate of
Origin (DCO). This document was created by the Linux Kernel community and is a
simple statement that you, as a contributor, have the legal right to make the
contribution. See the [DCO](DCO) file for details.
# Email and Chat
The project currently uses the general CoreOS email list and IRC channel:
- Email: [coreos-dev](https://groups.google.com/forum/#!forum/coreos-dev)
- IRC: #[coreos](irc://irc.freenode.org:6667/#coreos) IRC channel on freenode.org
## Getting Started
- Fork the repository on GitHub
- Read the [README](README.md) for build and test instructions
- Play with the project, submit bugs, submit patches!
## Contribution Flow
This is a rough outline of what a contributor's workflow looks like:
- Create a topic branch from where you want to base your work (usually master).
- Make commits of logical units.
- Make sure your commit messages are in the proper format (see below).
- Push your changes to a topic branch in your fork of the repository.
- Make sure the tests pass, and add any new tests as appropriate.
- Submit a pull request to the original repository.
Thanks for your contributions!
### Format of the Commit Message
We follow a rough convention for commit messages borrowed from AngularJS. This
is an example of a commit:
```
feat(scripts/test-cluster): add a cluster test command
this uses tmux to setup a test cluster that you can easily kill and
start for debugging.
```
The format can be described more formally as follows:
```
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
```
The first line is the subject and should be no longer than 70 characters, the
second line is always blank, and other lines should be wrapped at 80 characters.
This allows the message to be easier to read on GitHub as well as in various
git tools.
#### Subject Line
The subject line contains a succinct description of the change.
#### Allowed `<type>`s
- *feat* (feature)
- *fix* (bug fix)
- *docs* (documentation)
- *style* (formatting, missing semi colons, …)
- *refactor*
- *test* (when adding missing tests)
- *chore* (maintain)
#### Allowed `<scope>`s
Scopes can anything specifying the place of the commit change in the code base -
for example, "api", "store", etc.
For more details on the commit format, see the [AngularJS commit style
guide](https://docs.google.com/a/coreos.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit#).

## OEM configuration
The `coreos.oem.*` parameters follow the [os-release spec][os-release], but have been repurposed as a way for coreos-cloudinit to know about the OEM partition on this machine. Customizing this section is only needed when generating a new OEM of CoreOS from the SDK. The fields include:
- **id**: Lowercase string identifying the OEM
- **name**: Human-friendly string representing the OEM
- **version-id**: Lowercase string identifying the version of the OEM
- **home-url**: Link to the homepage of the provider or OEM
- **bug-report-url**: Link to a place to file bug reports about this OEM
coreos-cloudinit renders these fields to `/etc/oem-release`.
If no **id** field is provided, coreos-cloudinit will ignore this section.

#### oem #### update
The `coreos.oem.*` parameters follow the [os-release spec][os-release], but have been repurposed as a way for coreos-cloudinit to know about the OEM partition on this machine: The `coreos.update.*` parameters manipulate settings related to how CoreOS instances are updated.
- **id**: Lowercase string identifying the OEM - **reboot-strategy**: One of "reboot", "etcd-lock", "best-effort" or "off" for controlling when reboots are issued after an update is performed.
- **name**: Human-friendly string representing the OEM - _reboot_: Reboot immediately after an update is applied.
- **version-id**: Lowercase string identifying the version of the OEM - _etcd-lock_: Reboot after first taking a distributed lock in etcd, this guarantees that only one host will reboot concurrently and that the cluster will remain available during the update.
- **home-url**: Link to the homepage of the provider or OEM - _best-effort_ - If etcd is running, "etcd-lock", otherwise simply "reboot".
- **bug-report-url**: Link to a place to file bug reports about this OEM - _off_ - Disable rebooting after updates are applied (not recommended).
