=46rom a strict mathematical stand point of view, -a is not necessary =
when using -b with an aligned value.
Personally I don=E2=80=99t use the -a option of gpart anymore since it =
started to do funny magics in front of face. If I remember correct, =
gpart of the FreeBSD 9.x-RELEASES was still OK (or was it 8?). Nowadays, =
I align all my storage media by employing -b with a reasonable value.
