8a2fdf50ad use correct lxc-init path in sshd template
lxc-init got moved into SBINDIR/init.lxc recently.
This broke sshd template because path wasn't updated there.
This patch should fix this issue.

c63c04fcaf templates: improve refusing to run unprivileged
For all templates except lxc-ubuntu-cloud and lxc-download, detect not
only --mapped-uid but also --mapped-gid and error out.  Detecting will
not be done after -- parameter because of non-option parameters.

Also, change the mode of lxc-archlinux.in 100755 to 100644.

8ec981fc8b templates: Refuse to run unprivileged
Only the download and ubuntu-cloud templates work with unprivileged
containers, for all others, detect --mapped-uid and error out as early
as possible, recommending the use of the download template.

17abf2784d handle simple bashisms:
- [[ ]] -> [ ]
- == -> =
- source -> .
- redirect of fd 200 is error in mksh, use fd 9
- &> /dev/null -> > /dev/null 2>&1
- useless function keyword
- echo -e -> printf

still left bash shebang which did not validate with checkbashism, mostly
due 'type' being reported as bashism

f4d5cc8e1f sshd: Don't bind-mount /sbin/init read-write
lxc-sshd was mounting itself (the template script) as /sbin/init in the
container using a writable bind-mount.

This shouldn't be needed and could lead to quite a few problems should
one of those containers overwrite /sbin/init for some reason.

Instead simply move to a read-only bind-mount which should prevent any
accidental dammage.

18efb001a4 fix sshd template
Commit a0a2066d introduced an lxc subdir into the lxc-init path, but
this was never reflected in the sshd template. Add it there.

Don't have ssh-keygen ask for passphrase since host keys are not
supposed to use them.

Don't try to symlink kmsg since /dev is bind mounted readonly.

Read-only bind mount some extra /etc directories, and sysfs which are
needed by dhclient on Fedora and Oracle Linux. Fix mounting of /proc.

Find sshd in more places by adding some common paths to $PATH, and
use the found path to it instead of hardcoded /usr/sbin.

Check for ifconfig command, and print out container's IP address.

1897e3bcd3 Move container creation fully into the api
1. implement bdev->create:

python and lua: send NULL for bdevtype and bdevspecs.
They'll want to be updated to pass those in in a way that makes
sense, but I can't think about that right now.

2. templates: pass --rootfs

If the container is backed by a device which must be mounted (i.e.
lvm) then pass the actual rootfs mount destination to the
templates.

Note that the lxc.rootfs can be a mounted block device.  The template
should actually be installing the rootfs under the path where the
lxc.rootfs is *mounted*.

Still, some people like to run templates by hand and assume purely
directory backed containers, so continue to support that use case
(i.e. if no --rootfs is listed).

Make sure the templates don't re-write lxc.rootfs if it is
already in the config.  (Most were already checking for that)

3. Replace lxc-create script with lxc_create.c program.

Changelog:
May 24: when creating a container, create $lxcpath/$name/partial,
and flock it.  When done, close that file and unlink it.  In
lxc_container_new() and lxcapi_start(), check for this file.  If
it is locked, create is ongoing.  If it exists but is not locked,
create() was killed - remove the container.

May 24: dont disk-lock during lxcapi_create.  The partial lock
is sufficient.

14d9c0f09d Update for consistent indent
This commit updates all scripts using mixed indent to a consistent
4 spaces indent.

In the past quite a few of those scripts used tabs to instead of 8 spaces or
instead of 4 spaces, sometimes mixing those in the same line and sometimes
changing the tab width within the same file.

1881820ae4 lxc-create: Make location of container rootfs configurable
Make 'dir' an explicit backing store type, which accepts '--dir rootfs'
as an option to specify a custom location for the container rootfs.  Also
update lxc-destroy to now remove the rootfs separately, as removing
@LXCPATH@/$name may not hit it.

f02ce27d4b Add lxc.aa_profile example to all templates
LXC has optional apparmor support, default profile is lxc-container-default.
This change adds a commented "lxc.aa_profile = default" line to all templates,
uncommenting this will bypass apparmor for the container.

b91b1cd79c Let sshd template work on ubuntu systems.
/dev/shm is a symlink to /run/shm, so we need /run/shm
to exist in the container rootfs.  Also, /dev/mqueue does
not exist on the host, and can't be created by the container.
But we don't really need it so ignore that.
