Updated centos/fedora/oracle templates to use `hostname` for DHCP_HOSTNAME in
/etc/sysconfig/network/ifcfg-eth0, so the container's host name is propagated
to the host's DHCP server (e.g. dnsmasq, which also acts as the DNS server).
This resolves lxc/lxd#756

We were using 'all' controller if current was in all the
same cgroup.  That doesn't suffice.  We'd have to check
the target.  At that point we may as well just attach
controller by controller.

An optimization to consider is to check the /proc/initpid/cgroup
for all identical controllers.  Let's start by just getting it
right.

The yum in Centos 5.11 does not know about '--releasever', which is used by: lxc-create ... -- release=VERSION
The release version only needs to be set in the outer bootstrap, not the inner one.
With this change an lxc-create bootstrap of CentOS 5.11 completes enough to be usable.
CentOS 5.11 containers can be created, started, stopped, and networking works.

parameter. It allows root in userns to mount aufs.

This patch allows an unprivileged container to use aufs. The value of

to populate the list of subsystems to use.

Cgmanager can be started with some subsystems disabled (i.e.
cgmanager -M cpuset).  If lxc using cgmanager then uses the
/proc/self/cgroup output to determine which controllers to use,
it will fail when trying to do things to cpuset.  Instead, ask
cgmanager which controllers to use.

This still defers (per patch 1/1) to the lxc.cgroup.use values.

When running in posix mode (for example, because it was invoked as `sh`,
or with the --posix option), bash rejects the function names previously
used because they contain hyphens, which are not legal POSIX names, and
exits immediately.

This is a particularly serious problem on a system in which the
following three conditions hold:

1. The `sh` executable is provided by bash, e. g. via a symlink
2. Gnome Display Manager is used to launch X sessions
3. Bash completion is loaded in the (system or user) profile file
   instead of in the bashrc file

In that case, GDM's Xsession script (run with `sh`, i. e., bash in posix
mode) sources the profile files, thus causing the shell to load the bash
completion files. Upon encountering the non-POSIX-compliant function
names, bash would then exit, immediately ending the X session.

Fixes #521.

The lxc-debian template debootstraps a minimum debian system which does not contain dbus.
If systemd is used this will result in getty-static.service to be used instead of getty@ .
The systemd default files uses 6 tty's instead of the 4 the script creates.
This will lead to repeated error messages in the systemd journal.

(1) Add test for kernel version greater 3.
(2) Use && and || instead of -a and -o as suggested in
    http://www.unix.com/man-page/posix/1p/test/.

lxc-checkconfig will currently report "missing" on "Cgroup memory controller"
for kernel versions greater 3. This happens because the script, before checking
for the corresponding memory variable in the kernel config, currently will test
whether we have a major kernel version greater- or equal to 3 and a minor kernel
version greater- or equal to 6. This adds an additional test whether we have a
major kernel version greater than 3.

This breaks code that depended on the monitor being fully dead before
c->stop() returns.

This reverts commit 62e04161.

This breaks lxc-test-concurrent.

This reverts commit fef9aa89.

In the past, lxc-cmd-stop would wait until the command pipe was closed
before returning, ensuring that the container monitor had exited.
Now that we accept the actual success return value, lxcapi_stop can
return success before the monitor has fully exited.

So explicitly wait for the container to stop, when lxc-cmd-stop returned
success.

These are two fixes for long, long-standing bugs.

1. When we stop a container from the lxc_cmd stop handler, we kill its
init task, then we unfreeze the container to make sure it receives the
signal.  When that unfreeze succeeds, we were immediately returning 0,
without sending a response to the invoker.

2. lxc_cmd returns the length of the field received.  In the case of
an lxc_cmd_stop this is 16.  But a comment claims we expect no response,
only a 0.  In fact the handler does send a response, which may or may
not include an error.  So don't call an error just because we got back a
response.
