Hello, I try to use overlay for network boot clients using an NFS read-only filesystem. This works pretty well, except renaming files with the mv command fails: ========================== # ls -l -rw-r--r-- 1 root root 785 Mar 27 2016 foo # mv foo bar mv: cannot move 'foo' to a subdirectory of itself, 'bar' ========================== I mount the overlay filesystem as follows in the initrd, where /root is already mounted read-only from NFS: ========================== mkdir /writable mkfs.ext2 /dev/ram0 >/dev/null mount -n /dev/ram0 /writable >/dev/null mkdir /writable/upper mkdir /writable/work modprobe overlay mount -t overlay overlay -olowerdir=/root,upperdir=/writable/upper,workdir=/writable/work,default_permissions /root ========================== kernel version is 4.7.0-rc2, git cloned from git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git, using the overlayfs-next branch. is this a bug ? can I help anything debugging fixing this ?
