Also sets a marker file to poll IMDS.
The marker file is used for the following scenario: the VM boots into
this polling loop, which we expect to be proceeding infinitely until
the VM is picked. If for whatever reason the platform moves us to a
new host (for instance a hardware issue), we need to keep polling.
However, since the VM reports ready to the Fabric, we will not attach
the ISO, thus cloud-init needs to have a way of knowing that it should
jump back into the polling loop in order to retrieve the ovf_env.t PreprovisionedVms' Creating a marker file to poll imds: %ss {pid}: {time}

A fresh ephemeral disk is formatted by Azure and will:
a.) have a partition table (dos or gpt)
b.) have 1 partition that is ntfs formatted, or
have 2 partitions with the second partition ntfs formatted.
(larger instances with >2TB ephemeral disk have gpt, and will
have a microsoft reserved partition as part 1. LP: #1686514)
c.) the ntfs partition will have no files other than possibly
'dataloss_warning_readme.txt'
User can indicate that NTFS should never be destroyed by setting
DS_CFG_KEY_PRESERVE_NTFS in dscfg.
If data is found on NTFS, user is warned to set DS_CFG_KEY_PRESERVE_NTFS
to make sure cloud-init does not accidentally wipe their data.
If cloud-init cannot mount the disk to check for data, destruction
will be allowed, unless the dscfg key is set.s: config says to never destroy NTFS (%s.%s), skipping checksR! s device %s does not exists Resolving realpath of %s -> %si s device %s was not partitionedi s& device %s had 3 or more partitions: %sR8 i s5 partition %s (%s) on device %s was not ntfs formattedc S sG t d g � } t g t j | � D] } | j � | k r" | ^ q" � S( Ns dataloss_warning_readme.txt( t setR& R� t listdirt lower( t mpt ignoredt f( ( sE /usr/lib/python2.7/site-packages/cloudinit/sources/DataSourceAzure.pyt count_filesl s s1 partition %s (%s) on device %s was ntfs formattedR� s mount-ntfs-and-countR� R� R� t ntfst update_env_for_mountt Ct LANGs cannot mount ntfss unknown filesystem type 'ntfs's^ but this system cannot mount NTFS, assuming there are no important files.

@param paths: List of networking scripts or directories to remove when
present.
In certain supported ubuntu images, static udev rules or netplan yaml
config is delivered in the base ubuntu image to support dhcp on any
additional interfaces which get attached by a customer at some point
after initial boot. Since the Azure datasource can now regenerate
network configuration as metadata reports these new devices, we no longer
want the udev rules or netplan's 90-hotplug-azure.yaml to configure
networking on eth1 or greater as it might collide with cloud-init's
configuration.
Remove the any existing extended network scripts if the datasource is
enabled to write network per-boot.
