Consolidate lucid, maverick, natty, and oneiric templates into one 'ubuntu'
template.
Add support for specifying architecture.
Add support for '--trim|-x' option, which removes services like the lucid
template used to. This creates smaller, faster-booting containers, but they
will not be safe with certain upgrades, like mountall or udev. When -x is
not specified for lucid or maverick container, then install lxcguest from
the ubuntu-virt ppa, since it does not exist in the official archives, and
the container is not safe to boot without lxcguest.
Add support for '--bindhome <user>' option, which will cause /home/<user>
to be bind-mounted into the container, and create the user with his
original password, shell, and group memberships in the container.
changelog:
june 23:
lxc-ubuntu template: set lxc.arch in config
install lxcguest when NOT trimming the container

Create an lxc-clone script to clone containers. It should probably
be factored into helpers and then enhanced, in particular to convert
between LVM and non-LVM containers, create non-snapshot LVM clones,
support loopback devices, and, when stable enough, to use
overlayfs, btrfs, etc.
But this is a start.

When we accept a connection, we have to set the close-on-exec flag,
otherwise that won't be possible to reboot a container through a
lxc-console command.

'setns.h' is not an lxc interface.
Also, a side effect of this declaration of 'setns.h' in the lxc header
files is to be distributed in the lxc tarball. This breaks the
lxc-attach command because the file is not automatically generated at
compile time.

src/lxc/conf.c will explicitly mount it anyway. Furthermore, the fstab
entry, which is getting processed first, did not specify -o newinstance.
This can cause the host's devpts entry mount options to change, as in
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/607636.

The default appender for logs is currently the file one: this
make macros from log.h unusable as long as lxc_log_init() hasn't
been called. This prevents errors from even being printed on
stderr in lxc_caps_init() for example.
Let's make stderr the default appender.

lxc_cgroup_path_get currently cache the cgroup mount point plus the
container name at the same time, making every call of the function
returning the same value.
It mean that actually every call to lxc_cgroup_get with a different
container name will in fact use the same container name as used for
the primary call.
I join a patch to fix that, still doing some caching, but only caching
the cgroup moint point this time. This patch actually work for me, as
I am using the liblxc for retrieving statistics about all running
containers, using lxc_cgroup_get to retrieve every interesting values.

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.

container context or not.

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.

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.
