2018-07-09ubuntu,centos,debian: get_linux_distro to align with platform.distChad Smith
A recent commit added get_linux_distro to replace the deprecated python platform.dist module behavior before it is dropped from python. It added behavior that was compliant on OpenSuSE and SLES, by returning (<distro_name>, <distro_version>, <cpu-arch>). Fix get_linux_distro to behave more like the specific distribution's platform.dist on ubuntu, centos and debian, which will return the distribution release codename as the third element instead of <cpu-arch>. SLES and OpenSUSE will retain their current behavior. Examples follow: ('sles', '15', 'x86_64') ('opensuse', '42.3', 'x86_64') ('debian', '9', 'stretch') ('ubuntu', '16.04', 'xenial') ('centos', '7', 'Core') LP: #1780481
2018-05-29util: add get_linux_distro function to replace platform.distRobert Schweikert
Allow the user to set the distribution with --distro argument to setup.py. Fall back is to read /etc/os-release. Final backup is to use platform.dist() Python function. The platform.dist() function is deprecated and will be removed in Python 3.7 LP: #1745235
2018-04-26net: detect unstable network names and trigger a settle if neededRyan Harper
The cloud-init-local.service expects that any network device name changes have already been completed by the kernel or udev daemon. In some situations we've found that the renaming of interfaces from kernel names (eth0, eth1, etc) to their persistent names (eno1, ens3, enp0s1, etc) may happen after cloud-init-local has started where it reads values from sysfs about what network devices are present, and which device to use as a fallback nic. Subsequently, cloud-init-local would write out network configuration for a kernel device name which would no longer be present by the time that networking services start to bring up the devices. The result is that the instance does not get networking configured. Prior to use of systemd-networkd, the Ubuntu 'networking.service' unit included a call to udevadm settle which is why this race is not seen on a Xenial system. This change adds the ability to detect if an interface has a stable name, if if we find one without stable names and stable names have not been disabled (net.ifnames=0 in /proc/cmdline), then cloud-init will invoke udevadm settle.

2018-04-19pylint: pay attention to unused variable warnings.Scott Moser
This enables warnings produced by pylint for unused variables (W0612), and fixes the existing errors.
2018-03-23IBMCloud: Initial IBM Cloud datasource.Scott Moser
This adds a specific IBM Cloud datasource. IBM Cloud is identified by: a.) running on xen b.) one of a LABEL=METADATA disk or a LABEL=config-2 disk with UUID=9796-932E The datasource contains its own config-drive reader that reads only the currently supported portion of config-drive needed for ibm cloud. During the provisioning boot, cloud-init is disabled. See the docstring in DataSourceIBMCloud.py for more more information.
2018-03-14set_hostname: When present in metadata, set it before network bringup.Chad Smith
When instance meta-data provides hostname information, run cc_set_hostname in the init-local or init-net stage before network comes up. Prevent an initial DHCP request which leaks the stock cloud-image default hostname before the meta-data provided hostname was processed. A leaked cloud-image hostname adversely affects Dynamic DNS which would reallocate 'ubuntu' hostname in DNS to every instance brought up by cloud-init. These instances would only update DNS to the cloud-init configured hostname upon DHCP lease renewal. This branch extends the get_hostname methods in datasource, cloud and util to limit results to metadata_only to avoid extra cost of querying the distro for hostname information if metadata does not provide that information.

2018-03-09shellify: raise TypeError on bad input.Scott Moser
This makes 2 changes to shellify's behavior: a.) raise a TypeError rather than a RuntimeError. b.) raise a TypeError if input is not a list or tuple.
2018-01-24btrfs: support resizing if root is mounted ro.Robert Schweikert
Resize of btrfs fails if the mount point for the file system we are trying to resize, i.e. the root of the filesystem is read only. With this change we use a known (currently snapper specific) rw location to work around a flaw that blocks resizing of the ro filesystem. LP: #1734787
