This has been "best practice" for quite some time, and its a common
request of "where is the output of my user-data programs".

We were passing a unicode string to 'runcmd' in the path to the .crt file.
That is because the keyname was coming from ovf file as unicode.
Ie:
u'/var/lib/waagent/6BE7A7C3C8A8F4B123CCA5D0C2F1BE4CA7B63ED7.crt'
Then, logging was extending not appending errors.

Before passing a path into selinux.matchpathcon, it needs to be casted
to a string, since the path could be unicode and selinux.matchpathcon
does not support unicode.

This allows a general config option to prefix apt-get commands via
'apt_get_wrapper'. By default, the command is set to 'eatmydata', and the
mode set to 'auto'. That means if eatmydata is available (via which), it
will use it.
The 'command' can be either a array or a string.

This adds a debug module for printing debug output. It does not enable it
by default (by putting it in in cloud_config_modules or elsewhere).
Thats fine, as it is still quite useful for the user to run:
sudo cloud-init single --frequency=always --name=debug ci-debug.txt
|
|
Since the import failure can be an expected failure do not log that
failure at a WARNING level, but to start log it at a DEBUG level. This
will help in figuring out why imports fail (if they ever do) for developer
and cloud-init users. Previously it is hard to know if a module fails
importing for a valid reason (not existent) or an invalid reason (the
module exists but the module has a dependency which is not satisfied).

0.6.4 was never released, but had entries in the ChangeLog.
The lack of a tag for 0.6.4 caused problems with 'make rpm'

This removes the requirement for /proc/PID/mountinfo, which was added in linux
kernel 2.6.26. We could potentially re-visit this and read /proc/mounts rather
than /proc/mtab, but mtab proves effective in testing.

The expected behavior was that 'ephemeral0' in a mount device entry
and ephemeral0 mapped to /dev/xvdb that /dev/xvdb1 or /dev/xvdb would
be substituted.
Explicitly setting 'ephemeral0.0' would mean only xvdb in this case.

cloud-initramfs-growroot is an initramfs module in cloud-initramfs-tools
that resizes the root partition before the root is pivoted over.
growroot was used in Ubuntu up to and including 12.10. The file
/etc/growroot-disabled on the root filesystem was the only way of
disabling the growing of the root partition.
In cloud-init 0.7.2 cloud-init began resizing the root partition
as growpart gained the ability to utilize 'ptupdate' in kernels > 3.8.
This was a big improvement as now the user could disable or enable
the growing of the root partition via user-data.
In order to let users disable growing of / very simplistically cloud-init
will now respect the presense of /etc/growroot-disabled unless config
specifically tells it to ignore that file.

fix documentation of mkpasswd usage in
doc/examples/cloud-config-user-groups.txt
Also, Precise's version of pep8 insists on ordering of imports, but saucy's
has not. So we had some incorrect ordering. This fixes './tools/run-pep8'
on precise.

Ubuntu images in 12.04 added the user to the 'admin' group.
The admin group was deprecated/replaced with the 'sudo' group in 12.10.
d-i adds its first-user to the 'sudo' group, so it makes sense to mimic
that behavior for the default user created by cloud-init. That was the
original reason behind the presense in the 'admin' group.
Also, here I sorted alphabetically the group list.

When libselinux-python is installed, but selinux is disabled on the
instance, calls to restorecon blow up. This fixes it by checking what
is_selinux_enabled() returns first.

If the disks that are attached on boot do not have a filesystem
on them, then this module is useful to set that up.

A new field in the metadata has emerged on openstack config drive, one
that provides a way to seed the linux random generator.
This adds a 'random_seed' config module that writes and that it to
/dev/urandom. Also added is support for reading that data on
azure via the hyper-v acpi table data.
In config drive datasource, it rewrites parts of the on_boot code to use a
little helper class.

the resizepart code was not functional.
We will re-favor it later under bug 1212492.
For now, we'll just favor the 'growpart' resizer.
Both will be found in Ubuntu cloud images.

The reason for this is that more and more things I was wanting to be able to
see how long they took. This puts that time logic into a single place. It
also supports (by default) reading from /proc/uptime as the timing mechanism.
While that is almost certainly slower than time.time(), it does give
millisecond granularity and is not affected by 'ntpdate' having
run in between the two events.

This adds a very well defined and understood mechanism for applying changes to
the cloud-config. Had we seen this previously, we might have not done the
merge-types work.

Instead of previously initializing and not finalizing the handles that
completed successfully when a handler initializing or running failed we
should attempt to always give said handlers a chance to finalize (even
when another handler fails).

Changing password via 'chpasswd' command in rhel5 would fail, if input
to the 'chpasswd' command doesn't end with '\n'. The fix is just to
append a carriage return to the input.

Some code from the RHEL handler was moved to a new file so that it can
be used by the SLES handler.

This datasource is not perfect at this point, but is tested on raring.
It expects that walinuxagent config is set to disable provisioning
(Provisioning.Enabled=n) and also that walinuxagent will not start
otherwise (ie 'echo manual | sudo tee /etc/init/walinuxagent.override).

|
Previously we'd not invoked reload-configuration because doing so
caused issues with upstart. Now, instead, determine if we can invoke it.

This is not really a problem, because nothing would call transport_iso9660
with 'require_iso' as False, but if it did, then we would have still
required iso9660 filesystem on the mount.

This branch contains fixes found while investigating integration of cloud-init
into oVirt. They're in 3 categories:
- compatibility with systemd configuration management (as used in Fedora 18)
- workaround for a 2.6 kernel quirk which prevented 'blkid' from displaying
/dev/sr0 in some cases
- writing sysconfig files in typical convention, with a newline preceding EOF,
to make some parsers happy

dist-upgrade is generally more correct here to get all packages upgraded.
We add the options to change these in system_info. Also, document
the previous apt configuration change (apt_get_command).

This re-works the urlhelper and users of it to use requests rather
than urllib2. The primary benefit is that now when using recent
versions of python-requests (>= 0.8.8) https certificates will be checked.

This adds a very useful mechanism for merging cloud-config, allowing
the user to append to lists (ie, just add more 'run_cmd') or other
things.
See doc/merging.txt for more information, it is intended to be backwards
compatible by default.
LP: #1023179

This allows the customization of the apt-get command used for installing
packages, and also adds '--force-unsafe-io'. Because this is spawned from
cloud-init, it seems to make sense as a first boot package installation
option.

This adds support for resizing partition tables for mounted partitions.
It thus allows us to remove 'cloud-initramfs-growpart' from running in
the initramfs, and do it here instead.
That depends on:
a.) growpart in cloud-utils 0.2.7 or later
or
parted with 'resizepart' support
b.) kernel 3.8.

this fixes a confusing message, most commonly found in /var/log/dmesg
or seen on log screens:
init: cloud-init-nonet main process (307) killed by TERM signal
This was actually *expected* as the upstart job was supposed to block
until networking came up, and the SIGTERM was sent by upstart.
That said, the message was confusing. Now, instead we will see something like
cloud-init-nonet[6.54]: waiting 10 seconds for network device
cloud-init-nonet[12.13]: static networking is now up
Which is much nicer. In the event that networking does not come up
you'll see:
cloud-init-nonet[X.Y]: gave up waiting for a network device.

this fixes an issue where ssh keys were not being parsed correctly.
The result was that keys were considered to have options that did not
have options.
Additionally, those options were being written rather than the disable_root
options.
