 Thank you!  I will add -B to makefs.  So, is a powerpc build on LE
 platforms also affected?

 For sunlabel replacement I am trying gpart since g_part_vtoc8 is
 available as a kernel module even for non-sparc64 platforms.
 However, it is difficult to set CHS parameters manually.  In the ISO
 image generation script, I just concatenated an ISO image and a UFS
 image then wrote a VTOC8 label over it.  While this needs the offset
 parameter of the UFS image and it must be in cylinders, the
 sectors/cylinder parameter is dynamically determined by the media
 size.
