The existing code has two issues with btrfs:
1) The command to resize a btrfs filesystem uses a path to the mount
point, not the underlying device:
$ btrfs filesystem resize max /dev/vda1
ERROR: unable to resize '/dev/vda1' - Inappropriate ioctl for device
Resize '/dev/vda1' of 'max'
$ btrfs filesystem resize max /
Resize '/' of 'max'
2) The code that is given a path and finds the ID of the device where
the path is mounted doesn't work for btrfs:
Use /proc/$$/mountinfo to find the device where path is mounted.
This is done because with a btrfs filesystem using os.stat(path)
does not return the ID of the device.
Here, / has a device of 18 (decimal).
$ stat /
File: '/'
Size: 234 Blocks: 0 IO Block: 4096 directory
Device: 12h/18d Inode: 256 Links: 1

Find where / is mounted:
$ mount | grep ' / '
/dev/vda1 on / type btrfs (rw,subvol=@,compress=lzo)
And the device ID for /dev/vda1 is not 18:
$ ls -l /dev/vda1
brw-rw---- 1 root disk 253, 1 Jan 13 08:29 /dev/vda1
So use /proc/$$/mountinfo to find the device underlying the input
path.

This change adds the ability to provide specific package versions to
Distro.install_packages and subsequently Distro.package_command. In order
to effectively use Distro.install_packages, one is now able to pass a
variety of formats in order to easily manage package requirements.
These are examples of what can be passed:
- "package"
- ["package1","package2"]
- ("package",)
- ("package", "version")
- [("package1",)("package2",)]
- [("package1", "version1"),("package2","version2")]
This change also adds the option to install a specific version for the
puppet configuration module. This is especially important here as
successful puppet deployments are highly reliant on specific puppet
versions.

Right now, all distros but ubuntu will fail to manage /etc/hosts.
This is due to the fact that the templates are named:
- hosts.ubuntu.tmpl
- hosts.redhat.tmpl
The config handler is specifically looking for a template with the
given distro name.
This change addresses this issue.

Quick chat with ctracy indicated that this is just as well run
PER_INSTANCE, and it is more consistent with other things that way.

Managing resolv.conf can be quite handy when running in an environment
where you would like to control DNS resolution, despite being provided
DNS server information by DHCP. This module will allow one to define the
structure of their resolv.conf and write it PER_ONCE.
Right now this makes the most sense on RedHat, and therefore, has defined 'distros' as such.
Note that when a config drive is used, and dhcp is not used that this module
may not be applicable since in the RedHat based distros the config drive typically
contains a ubuntu style network configuration which contains nameservers that can
be used in /etc/resolv.conf, but for other types of datasources it is useful to
have a module which can be specifically configured to write out /etc/resolv.conf

Forgot to pass cfg to this function, and thus this would have never
worked.

is due to the fact that the templates are named:
- hosts.ubuntu.tmpl
- hosts.redhat.tmpl
The config handler is specifically looking for a template with the

This change addresses this issue and is contingent upon support of
'osfamilies' as implemented in LP: #1100029
(lp:~craigtracey/cloud-init/osfamilies)
|
|
often it is convenient to classify a distro as being part of an
operating system family. for instance, file templates may be
identical for both debian and ubuntu, but to support this under
the current templating code, one would need multiple templates for the
same code.
similarly, configuration handlers often fall into the same bucket: the
configuraton is known to work/has been tested on a particular family
of operating systems. right now this is handled with a declaration
like:
distros = ['fedora', 'rhel']
this fix seeks to address both of these issues. it allows for the
simplification of the above line to:
osfamilies = ['redhat']
and provides a mechanism for operating system family templates.

This adds 'omnibus' to the values supported for chef's "omnibus_url" config
option. It also:
* makes 'omnibus_url' configurable in cloud-config.
* adds a 'force_install' flag, to allow the install code to
act even if /usr/bin/chef-client is already present.

when /etc/ca-certificates.conf is read by update-ca-certificates
lines after a blank line get ignored. Here, ensure that
there are no blank lines, and no duplicate entries for cloud-init are
added.

resize_root: noblock
has been broken in the 0.7.0 series. Using it would disable resizing.

the migrator was not renaming items in the "cloud" semaphore path.
Those were items that would run once only.
Now we just check both ipath('sem') and cpath('sem')
|
|
this adds 'power-state-change' config module that allows the user to
specify in cloud-config syntax that a system reboot or shutdown should occur
after cloud-init is done.

The sleep is added here simply to not completely spin cpu on waiting
for the parent pid to die.
the allowing of errno 3 is because I was getting this. I dont have
a perfect explanation, but I suspect that the 'open' was actually
getting this back from the /proc filesystem after the pid had died.
Possibly in the window between when the 'open' was done and the 'read()'
was done.

This allows the user to easily run stuff even after cloud-init-final
has finished. The initial reason for it is to be able to run
/sbin/poweroff and not have cloud-init complain loudly that it is
being killed.

This migrator module does a few things
* fixes filename markers that were written with a '-' in them to have
an '_' instead
* support renaming modules. Explicitly this handles the name change
of 'apt-update-upgrade' to 'apt-configure' and
'package-update-upgrade-install'
Also, just be more consistent everywhere where writing semaphore/marker
files and use '_' instead of '-' (canon_sem_name).

the fully qualified domain name should end
up in /etc/sysconfig/network by passing the
fqdn to the update and set hostname methods
and using it accordingly.

is actually a valid value returned.
2. Adjust variable naming
|
|
when applying the canon routine.
2. Add in a function to migrate legacy
semaphores to new semaphores.
|
|
that can be used to aid in the moving
of older versions of cloud-inits data
to newer versions of cloud-inits data.
1. Move the semaphores for the current instance
to there canonicalized names and use the
canonicalized in the file 'locking' code
|
|
2. Added example cloud-config
3. Added functioning test for yum config
|
|
1. Remove the usage of the path.join function now that all code should
be going through the util file methods (and they can be mocked out as
needed).
2. Adjust all occurences of the above join function to either not use it
or replace it with the standard os.path.join (which can also be mocked
out as needed)
3. Fix pylint from complaining about the tests folder 'helpers.py' not
being found.
4. Add a pylintrc file that is used instead of the options hidden in the
'run_pylint' tool.

that removes some of the code in apt_update_upgrade
to do upgrades and installs and places it in a
generic package module and adjusts some of the
reboot backoffs and log flushing/sleeping that
was happening there.

write out the yum.repo format for those
that want to hook into different repos
for installing.
|

setup properly.
