Until support for bonding params is added to networkd, this will be
neccessary in order to use bonding parameters (i.e. miimon, mode).
This also makes it such that the 8012q module will only be loaded if
the network config makes use of VLANs.
In order for networkd to properly configure the network interfaces, the configs must be
prefixed to ensure that they load in the correct order (parent interfaces have a lower
prefix than their children).
Adding the flag -convertNetconf which is used to specify the config
format to convert from (right now, only 'debian' is supported).
Once the network configs are generated, they are written to
systemd's runtime network directory and the network is restarted.
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.
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.
When using openssh without pam it checks for a ! prefix in the password
field, locking the account entirely if found. The other common lock
character, *, is allowed by ssh to login via ssh keys so use it instead.
