Thanks Daniel!
The linux-3.0 patches don't seem to be working for me unfortunately.
I compiled lxc-0.7.5 with the patched linux-3.0. After starting a container
foo via lxc-execute,I ran the following command:
$ lxc-attach -n foo -- /bin/bash
When I run lxc-attach, I get the following error:
I just tried running lxc-attach with linux-2.6.38. I got the same error as
with linux-3.0 -- Function not implemented - failed to set namespace 'pid'.
Here's the exact sequence of steps that I followed:

Just to be sure that wasn't the case, I tried running the executable
directly from the lxc source directory. I got the same error:
$ cd src/lxc
$ ./lxc-execute -n foo -f /etc/mn/host.conf -- /bin/bash
root@mnhost:/home/nikhilh/lxc/src/lxc#
In another terminal:
$ cd src/lxc
$ ./lxc-attach -n foo
If I understand the lxc code right, it's failing in the function
get_cgroup_mount in src/lxc/cgroup.c, which tries to read the cgroup mount
point from /proc/mounts.
/proc/mount seems to be fine on my machine:
$ cat /proc/mounts
...
...
cgroup /cgroup cgroup

I've done a quick try of the patches with linux-3.0.4 with lxc-0.7.5,
slackware64-13.37 and my existing containers and I'm able to turn them
off easily with
lxc-attach -n mycontainer -- /sbin/halt

I'll test them more, but in the
Thank you, Daniel. If lxc-attach enters the mainline kernels it will, with
the LANA netgraph implementation, become a powerful tool for network
simulation. The only component inside the kernel that is still missing are
union mounts.
