Arch linux lxc in debian host.

Question

Hi. I have been playing with lxc recently. Im running them on a debian host. I have created a couple of debian lxc and a centos lxc inside the host. Now im trying to create an arch lxc. There is an arch linux template provided by the debian package but it requires pacman installed on the host system in order to work. This is a production server and i dont want to install binaries untracked, so compiling pacman with make, is not an option.
I decided to create an Arch linux chroot as the wiki says by dowloading a tarball.
Im able to chroot sucessfully to it and install some packages. I have created the lxc dev/  files by following the arch wiki, and reading the archlinux template. Then i created a config file for the linux container and a fstab file. I got these from the archlinux template and copying other lxc config and fstab files (debian and centos one).
However hen i try to boot the container with lxc-start i got
lxc-start: File exists - failed to symlink '/dev/pts/ptmx'->'/dev/ptmx'
lxc-start: failed to setup the new pts instance
lxc-start: failed to setup the container
lxc-start: invalid sequence number 1. expected 2
lxc-start: failed to spawn 'arch'
So i remove /dev/ptmx  into the lxc.
Then i got:
lxc-start: No such file or directory - failed to exec /sbin/init
lxc-start: invalid sequence number 1. expected 2
lxc-start: failed to spawn 'arch
And here im trapped, i cant find /sbin/init, it doesn't exist, in a normal arch installation /sbin/init is pointing to /lib/systemd/systemd .
What to do now?? Is it impossible to setup a lxc with arch inside  a systemv hosts system?????
here is my config file:
xc.utsname=arch
lxc.tty=4
lxc.pts=1024
lxc.rootfs=/srv/lib/lxc/arch/rootfs
lxc.mount=/srv/lib/lxc/arch/fstab
#networking
#lxc.network.type=${lxc_network_type}
#lxc.network.flags=up
#lxc.network.link=${lxc_network_link}
#lxc.network.name=eth0
#lxc.network.mtu=1500
#cgroups
lxc.cgroup.devices.deny = a
# /dev/null and zero
# /dev/null and zero
lxc.cgroup.devices.allow = c 1:3 rwm
lxc.cgroup.devices.allow = c 1:5 rwm
# consoles
lxc.cgroup.devices.allow = c 5:1 rwm
lxc.cgroup.devices.allow = c 5:0 rwm
lxc.cgroup.devices.allow = c 4:0 rwm
lxc.cgroup.devices.allow = c 4:1 rwm
# /dev/{,u}random
lxc.cgroup.devices.allow = c 1:9 rwm
lxc.cgroup.devices.allow = c 1:8 rwm
# /dev/pts
lxc.cgroup.devices.allow = c 136:* rwm
# rtc
lxc.cgroup.devices.allow = c 254:0 rwm
and fstab
proc proc proc nodev,noexec,nosuid 0 0
sysfs sys sysfs defaults 0 0

I'm not sure if you've tried Docker yet, but it took about 3 minutes to have a working Arch Docker container on my Ubuntu 12.04 server:
# docker pull base/arch
# docker run -i -t base/arch /bin/bash
[root@c21eea45fb46 /]# pacman -Syu
