Yes, there's an NFSv4 related splat because overlayfs can't copy up "system.nfs4_acl" xattr. The weird but apparently unfixable fact is that this attribute is there even if the nfs4-acl is equivalent to the DAC bits (i.e. the common case). If you don't want to use NFS acls, then just turn them off with "noacl" mount option on the NFS mount and things should work.
