--------------- cloud-init (0.7.8-49-g9e904bb-0ubuntu1~16.04.1) xenial-proposed; urgency=medium * debian/cloud-init.postinst: update /etc/fstab on Azure to fix future resize operations. (LP: #1611074) * New upstream snapshot. - Add activate_datasource, for datasource specific code paths. (LP: #1611074) - systemd: cloud-init-local use RequiresMountsFor=/var/lib/cloud (LP: #1642062) cloud-init (0.7.8-47-gb6561a1-0ubuntu1~16.04.1) xenial-proposed; urgency=medium * debian/cloud-init.templates: enable DigitalOcean by default [Ben Howard] * New upstream snapshot. - systemd/cloud-init-local.service: + replace 'Wants' and 'After' on local-fs.target with more granular After=systemd-remount-fs.service and RequiresMountsFor=/var/lib and Before=sysinit.target. This is done run sufficiently early enough to update /etc/fstab. (LP: #1611074) + add Before=NetworkManager.service so that cloud-init can render NetworkManager network config before it would apply them. - systemd/cloud-init.service: + add Before=sysinit.target and DefaultDependencies=no (LP: #1611074) + drop Requires=networking.service to work where networking.service is not needed. + add Conflicts=shutdown.target + drop unnecessary Wants=local-fs.target - net: support reading ipv6 dhcp config from initramfs [LaMont Jones] (LP: #1621615) - dmidecode: Allow dmidecode to be used on aarch64, and only attempt usage on x86, x86_64, and aarch64. [Robert Schweikert] - disk-config: udev settle after partitioning in gpt format. (LP: #1626243) - Add support for snap create-user on Ubuntu Core images. [Ryan Harper] (LP: #1619393) - Fix sshd restarts for rhel distros. [Jim Gorz] - Move user/group functions to new ug_util file [Joshua Harlow] - update Gentoo initscripts to run in the correct order [Matthew Thode] - MAAS: improve the debugging tool in datasource to consider config provided on kernel cmdline. - lxd: Update network config for LXD 2.3 [Stéphane Graber] (LP: #1640556) - Decode unicode types in decode_binary [Robert Schweikert] - Allow ephemeral drive to be unpartitioned [Paul Meyer] - subp: add 'update_env' argument which allows for more easily adding environment variables to a subprocess call. - Adjust mounts and disk configuration for systemd. (LP: #1611074) - DataSources: + Ec2: protect against non-dictionary in block-device-mapping. + AliYun: Add new datasource for Ali-Cloud ECS, that is available but not enabled by default [kaihuan.pkh] + DigitalOcean: use meta-data for network configuration and enable data source by default. [Ben Howard] + OpenNebula: replace parsing of 'ip' command with similar function available in cloudinit.net. This fixed unit tests when running in environment with no networking. - doc changes: + Add documentation on stages of boot. + make the RST files consistently formated and other improvements. + fixed example to not overwrite /etc/hosts [Chris Glass] + fix spelling / typos in ca_certs and scripts_vendor. + improve HACKING.rst file + Add documentation for logging features. [Wesley Wiedenmeier] + Improve module documentation and doc cleanup. [Wesley Wiedenmeier] - code style and unit test changes: + pep8: fix style errors reported by pycodestyle 2.1.0 + pyflakes: fix issue with pyflakes 1.3 found in ubuntu zesty-proposed. + Add coverage dependency to bddeb to fix package build. + Add coverage collection to tox unit tests. [Joshua Powers] + do not read system /etc/cloud/cloud.cfg.d (LP: #1635350) + tests: silence the Cheetah UserWarning about NameMapper C version. + Fix python2.6 things found running in centos 6. -- Scott Moser <smo...@ubuntu.com> Fri, 18 Nov 2016 16:51:54 -0500 ** Changed in: cloud-init (Ubuntu Xenial) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Yahoo!

If my user-data includes any non-default username, creation fails due to the read-only nature of the image. This is addressed by useradd/groupadd including a command line flag, --extrausers which instructs the command to look for a different user/group database in /var/lib/extrausers , which is writable in the ubuntu-core 16 image. [Test Case] In a snappy image that has cloud-init enabled, launch image with the following user-data: #cloud-config users: - name: bob snapuser: b...@bobcom.io And also: #cloud-config snappy: email: b...@bobcom.io where 'b...@bobcom.io' is your launchpad registered email address. Assume you can log in. [Regression Potential] The code is intended to be backwards compatible and inert unless cloud-config provided turns it on. It is also gated by a 'system_is_snappy' method that checks if the system is snappy (ubuntu core). Unit tests are provided, so regression should be somewhat reduced. Some code was moved around to implement this, and a new config module was added. [Other Info] The upstream change made here is at [1] [1] https://git.launchpad.net/cloud- init/commit?id=d8534561ba76db25b6fc0044eb1bfda63686e859 === End SRU Template === When running under ubuntu-core 16 images, /etc/passwd is read-only.

This is addressed by useradd/groupadd including a command line flag, --extrausers which instructs the command to look for a different user/group database in /var/lib/extrausers , which is writable in the ubuntu-core 16 image. The cc_user_groups module though is not aware of this. The Distro base-class could check if the system it's running on is snappy (see cc_snappy.py) and if so, append the --extrausers parameter to the useradd/groupadd commands. 1) release is Xenial (ubuntu-core 16) 2) cloud-init present is: 0.7.7~bzr1256-0ubuntu1~16.04.1 3) useradd bob -m should create the user bob 4) useradd fails due to readonly /etc/{passwd,group,shadow} To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1619393/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
