[lxc-devel] lxc 0.7.4 does not mount anything

hi,
i'm using this minimal config:
lxc.utsname = c0
lxc.mount.entry = none /lxc/c0/proc proc defaults 0 0
lxc.rootfs = /lxc/c0/
but lxc does not mount proc into /lxc/c0/proc.
using lxc.mount = /path/to/fstab also does not work.
it's also not only proc, it does not mount anything.
mounting within the container works fine.
but i want do drop cap_sys_admin.
to test the issue i'm using this command:
strace -f /opt/lxc/bin/lxc-start -n c0 -- /bin/ps > log.txt 2>&1
/bin/ps writes:
Error, do this: mount -t proc none /proc
so, /proc is not mounted.
i double checked it using /bin/bash as init...
log.txt is attached. you can see proc gets never mounted to /lxc/c0/proc/
is this a configuration error or a bug?

Thanks,
//richard
