Hi guys,

I was trying to run a container from ramfs, to root filesystem is
rootfs(ramfs), the template is put onto a mounted disk whose fs is
ext3, and I got this error(I'll skip my config and version and os
and so on, I think they are not keys):
...
lxc-start 1386999058.944 DEBUG    lxc_conf - mountpoint for old rootfs is 
'/usr/local/lib/lxc/rootfs/lxc_putold'

lxc-start 1386999058.944 ERROR    lxc_conf - failed to set rootfs for 'hq91'
lxc-start 1386999058.944 ERROR    lxc_start - failed to setup the container
lxc-start 1386999058.944 ERROR    lxc_sync - invalid sequence number 1. 
expected 2
lxc-start 1386999058.952 ERROR    lxc_start - failed to spawn 'hq91'

I dug and figured out that pivot_root has some limitations with ramfs,
So is it possible to run a container from ramfs? And how can we do that?

Any comments are appreciated.
