[Bug 1054035] Re: Adding default user fails due to lack of 'netdev' group
Neil, I'm curious as to what you tihnk the right behavior would be here. a.) add the netdev user b.) fail as it does now. ** Changed in: cloud-init (Ubuntu) Status: New = Triaged ** Changed in: cloud-init (Ubuntu) Importance: Undecided = Medium -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/1054035 Title: Adding default user fails due to lack of 'netdev' group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1054035/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1054035] Re: Adding default user fails due to lack of 'netdev' group
Is the netdev *group* used by Ubuntu server?
The way I've done it myself prior to Quantal is to delegate the problem
to the user-setup package.
add_default_user() {
echo Setting up '${CLOUD_DEFAULT_USERNAME}' default user
debconf-set-selections EOF
user-setup passwd/username string ${CLOUD_DEFAULT_USERNAME}
user-setup passwd/user-fullnamestring Default Cloud User
user-setup passwd/user-password-cryptedstring !
EOF
user-setup
}
Certainly I'd expect the default user to get created. I'd consider the current
failure to be an error.

[Bug 1054035] Re: Adding default user fails due to lack of 'netdev' group
I'm not sure I understand. The way to handle this in cloud-init now is just to be more explicit with your user-data or config (/etc/cloud/cloud.cfg.d). #cloud-config groups: - foogroup users: - name: ubuntu primary-group: foogroup Then you'll get what you asked for. In the past if the user 'ubuntu' did not exist, it would not be created at all. Now, if no 'users' item is specified in config, then it expects that the default user can be created. So, since that default user cannot be created, it is at least arguable that the right path is to fail. Creating groups not explicitly requested by the user would seem wrong. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/1054035 Title: Adding default user fails due to lack of 'netdev' group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1054035/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
Re: [Bug 1054035] Re: Adding default user fails due to lack of 'netdev' group
Why are you creating a default user in the 'netdev' group by default when the standard Ubuntu server installation doesn't appear to create that group? That doesn't make any sense. It's always going to fail. On 24 September 2012 16:24, Scott Moser smo...@ubuntu.com wrote: I'm not sure I understand.

I suppose this is probably for historical reasons. For all versions of our cloud images (hardy+), there was a 'netdev' user in which the 'ubuntu' was present (it is added by 'vmbuilder'). 'netdev' is also present in 2 ubuntu server installations i have (admittedly likely done via the network installer). It is related to network-manager, clearly not important for server, but still there nonetheless (https://wiki.ubuntu.com/Security/Privileges) So its not going to fail in most cases. I agree that it seems un-necessary, but I'd rather leave it as is then change the default groups that the user is in. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/1054035 Title: Adding default user fails due to lack of 'netdev' group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1054035/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

But the current stuff uses live-build - my system is derived from the
scripts that builds your cloud images.
And the hook in 030-create-user.chroot disable user creation for
Quantal.
if dist_ge ${codename} quantal; then
echo User creation on 12.10 is handled by cloud-init.
exit 0
fi
Netdev is created in a 025 default group hook.
echo Adding admin group...
addgroup --system --quiet admin
echo Adding netdev group...
addgroup --system --quiet netdev
Why have the hooks creating the default groups? Shouldn't they be in
the standard server installation packages so that a debootstrapped
Ubuntu system has the expected /etc/group layout?
