Hi, Mr. Okajima,
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.
For example, it will fail to run: "useradd {newuser}" in the
container's bash. The result is : "useradd: failure while writing
changes to /etc/shadow"
My nfs version is nfsv4, and aufs is aufs4, and LXC is the latest
version.
Please help me , thanks very much.
Best Regards.
Michael Mao
