When run in a zone, the host OS will look for /var/svc/provisioning

after meta-data is successfully retrieved and from this point
the host considers the provision of the zone to be a success and
keeps the zone running.

d�Z� Z S )� JoyentMetadataLegacySerialClienta� V1 of the protocol was not safe for all values.
Thus, we allowed the user to pass values in as base64 encoded.
Users may still reasonably expect to be able to send base64 data
and have it transparently decoded. So even though the V2 format is
now used, and is safe (using base64 itself), we keep legacy support.
The way for a user to do this was:
a.) specify 'base64_keys' key whose value is a comma delimited
list of keys that were base64 encoded.
b.) base64_all: string interpreted as a boolean that indicates
if all keys are base64 encoded.
c.) set a key named b64-<keyname> with a boolean indicating that
<keyname> is base64 encoded.r� Nc s( t t| �}|j|||� d | _d | _d S )N)r� r� r$ r r )r2 r r� r8 �s)r� r3 r4 r$ � s

Write the content to content_f. Under the following rules:
1. If no content, remove the file
2. Write the content
3. If executable and no file magic, add it
4. If there is a link, create it
@param content: what to write
@param content_f: the file name
@param backup_d: the directory to save the backup at
@param link: if defined, location to create a symlink to
@param shebang: if no file magic, set shebang

Becuase of the way that Cloud-init executes scripts (no shell),
a script will fail to execute if does not have a magic bit (shebang) set
for the file. If shebang=True, then the script will be checked for a magic
bit and to the SmartOS default of assuming that bash.

SMARTOS sdc:nics configuration data
sdc:nics data is a dictionary of properties of a nic and the ip
configuration desired. Additional nic dictionaries are appended
to the list.
Converting the format is straightforward though it does include
duplicate information as well as data which appears to be relevant
to the hostOS rather than the guest.
For each entry in the nics list returned from query sdc:nics, we
create a type: physical entry, and extract the interface properties:
'mac' -> 'mac_address', 'mtu', 'interface' -> 'name'. The remaining
keys are related to ip configuration. For each ip in the 'ips' list
we create a subnet entry under 'subnets' pairing the ip to a one in
the 'gateways' list.
Each route in sdc:routes is mapped to a route on each interface.
The sdc:routes properties 'dst' and 'gateway' map to 'network' and
'gateway'. The 'linklocal' sdc:routes property is ignored.
