I think it's exceedingly unlikely that anyone is going to unpack, and
subsequently boot, an Ubuntu root tarball on a filesystem that doesn't
support xattrs. All the filesystems that Ubuntu supports out of the box as
rootfs (in terms of installers, and filesystem tools preinstalled) support

Steve Langasek Give me a lever long enough and a Free OS
