Comment 7 for bug 1168526

No, I cannot reproduce this with the latest upstream kernel build
(3.9.0-030900rc7-generic #201304171402)

What I did:

sudo lxc-create -t ubuntu- n r1
cat > exit0.c << EOF
#include <stdlib.h>
int main() {
exit(0);
}
EOF
make exit0
sudo cp exit0 /var/lib/lxc/r0/rootfs/bin/
sudo lxc-start -n r1 -- /bin/exit0

Which only shows

lxc-start: No such file or directory - stat(/proc/2620/root/dev/lxc/console)

but exits 0 correctly. If I do

sudo lxc-start -n r1 -l info -o outout -- /bin/exit0

then outout shows:

      lxc-start 1366317913.390 INFO lxc_start - init has already exited

Are you sure when you tested the newer kernel you weren't using a different (unpatched) lxc?
