This change creates a few simple interfaces for coreos-specific
configuration options and moves things to them wherever possible; so if
an option needs to write a file, or create a unit, it is acted on
exactly the same way as every other file/unit that needs to be written
during the cloud configuration process.
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 580460ff3f0dba4aa6ba655d54965cbfd184137a.
Fix#69 - A user may provide an `enable` attribute of a unit in their
cloud config document. If true, coreos-cloudinit will instruct systemd
to enable the associated unit. If false, the unit will not be enabled.
Fix#71 - The default enable behavior has been changed from on to off.
The update_engine parsing and XML generation code is very naive. Instead
of trying to implement a correct parser and generater in C++ just
generate a file that doesn't have quote's around fields that we know
won't have spaces.
