@qclzdh the problem is that you have libacl on your system but they are either just stubs or RouDi is not privileged for the calls. From the errror messages it is more probable that the lib contains just stubs. Do you have access to a working libacl?

Thanks, i fixed this by add following config in my kernel, maybe this can be added in some doc~
CONFIG_TMPFS_POSIX_ACL=y
CONFIG_TMPFS_XATTR=y
