[Bug 918327] Re: lxc-start exits success on failure when non-root
Ok, I'm actually not sure what we should do about this. '-d' doesn't just mean don't show a console, it means daemonize. It does this by calling daemon(3), which forks(), lets the child continue, and exits success. We could toss extra checks in before the call to daemon(3) to check for privilege, but there are plenty of other reasons why the start could fail. So it seems we can do one of two things: 1. rewrite lxc-start so that it manually forks and waits for a message from the lxc monitor saying the container started, and only then exit 2. tell users that 'lxc-start -d' provides no information about the success of starting the container, and that if you care, you should call something like lxc-wait -n container -s RUNNING after the lxc-start to make sure it succeeded. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/918327 Title: lxc-start exits success on failure when non-root To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/918327/+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 918327] Re: lxc-start exits success on failure when non-root
Another (likely related) issue, after using sudo to start the container, observe: $ lxc-ls lv1 $ sudo lxc-start -n lv1 -d $ lxc-ls lv1 /usr/bin/lxc-ls: line 35: cd: /sys/fs/cgroup/cpuset///lxc: Permission denied ls: cannot access lv1: No such file or directory $ sudo lxc-ls lv1 lv1 $ sudo lxc-list RUNNING lv1 STOPPED So, as it is now after starting the container 'sudo lxxc-ls' shows 2 containers, but 'lxc-ls' (without sudo) shows annoying messages. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/918327 Title: lxc-start exits success on failure when non-root To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/918327/+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
