what is this -b -2048 business? we just want -b 2048.

Nevermind, that's valid:

  If  block-
              size  is preceded by a negative sign ('-'), then mke2fs will use
              heuristics to determine the appropriate  block  size,  with  the
              constraint  that  the  block  size  will  be at least block-size
              bytes.  This is useful for certain hardware  devices  which  re‐
              quire that the blocksize be a multiple of 2k.
