[lxc-users] LXC unpreviliged problem with aufs mounted on nfs

[homalu at 163.com]

Hi, All,
    I am working on my project that needs to use aufs as a backend for the LXC. 
    If I set the local branch as the first rw branch for aufs, as: 
        mount -t aufs -o br=/home/{lxcname}/data=rw:/home/base/rootfs=ro none /var/lib/lxc/containers/{lxcname}/rootfs
    the LXC works well in unpreviliged mode, I can modify any file in the container's bash as a root user.
    Buf if I set the nfs branch as the first rw branch, as:
        mount -t aufs -o br=/nfsmountpoint=rw:/home/base/rootfs=ro none /var/lib/lxc/containers/{lxcname}/rootfs
    the LXC can start up in unpreviliged mode, but I can't modify the files which's ownner is not root. It seems not working in unpreviliged mode.
    My nfs version is nfsv4, and LXC is the latest version.

    Please help me , thanks very much.
    
    Best Regards.

Michael Mao
