* Fix paths in the lxc-busybox templateDaniel Lezcano2011-01-281-4/+4
| | | | | | | | | | | | | | | | | | | | Author of the patch : Jonathan Liu <???> posted as a bug fix on the lxc sourceforge website. OS: Arch Linux 32-bit /etc/init.d/rcS do not use full path to syslogd, mount and udhcpc executables. As busybox requires /proc mounted if CONFIG_BUSYBOX_EXEC_PATH="/proc/self/exe" to run these commands without full path, the full path should be used in the startup script as /proc is mounted later in the script. It also fails to start the machine if /lib64 does not exist on the host system as there is a mount entry for /lib64 in the config. The attached patch changes commands in /etc/init.d/rcS to use full path and adds a check for /lib64 on host before adding lib64 mount entries to config.

* suppress udev log outputDaniel Lezcano2011-01-232-0/+6
| | | | | | | | | | | We use udev within these containers and we prevent the /dev files to be created with the cgroup whitelist. So when the udevd receives the event from the kernel, it will fail to create some nodes in /dev and will spit error on the console. We set the log level to zero, so udev will silently fail.

* Update ubuntu templatesSerge Hallyn2011-01-227-12/+597
| | | | | | | | | | | | | | | Rename 'ubuntu' template to 'lucid' Add new maverick and natty templates, which do much less tweaking of the environment. These should only be used on a kernel which supports sysfs tagging for /sys/class/net, as udev will be running in the container. The natty template needed to slightly change the installed packages for dhclient to be correclty installed.

* Fix mntflags initializationJoerg Gollnick2011-01-161-0/+1
| | | | | | | | | | Dear all, while setting up a container on x86_64 (archlinux host/guest) I had trouble with mounting dev/pts and others from container.fstab and a ssh login does not work (only ssh container bash -i gives you a shell) The cause is that conf.c does not initialize mntflags.

* fix the ns_cgroup vs clone_childrenDaniel Lezcano2011-01-091-6/+76
| | | | | | | | | | | | | | | | | | The following patch fixes the bug where the clone_children compatibility flag is available with the ns_cgroup subsystem. The 2.6.37 kernel version should be the only one which is concerned by this modification, please refer to Documentation/feature-removal-schedule.txt and look for ns_cgroup. The problem is coming from we check for clone_children and we set it automatically and then we try to create a new cgroup. As the ns_cgroup is present the cgroup already exists and we are not allowed to attach our pid to a new cgroup. The next error will be when we try to create a new container because we enabled the clone_children flag and the ns_cgroup is present, it is not allowed by the kernel. The patch fix this by checking the mount options. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com>

* Make mount paths relative to rootfsMichael Tokarev2010-12-171-8/+37
| | | | | | | | | | | | | | | | | | | | | | | | Why not chdir into the root of container right when the root filesystem is (bind-)mounted, and let all mount entries to be relative to the container root? Even more, to warn if lxc.mount[.entry] contains absolute path for the destination directory (or a variation of this, absolute and does not start with container root mount point)? This way, all mounts will look much more sane, and it will be much easier to move/clone containers - by changing only lxc.rootfs. I do it this way locally since the beginning, by chdir'ing to the proper directory (rootfs) before running lxc-start (in a startup script), but this is now broken in 0.7.3 which bind-mounts rootfs somewhere in /usr/lib/lxc.
