[issue1622] devfs doesn't create my ad4s3 (macbook)

Alex Hornung <[e-mail]> added the comment:

It seems gpt starts numbering slices at 0, so the usual ad4s1 is ad4s0, ...=
=20
leading to the fact that the expected ad4s3 is at ad4s2.

In any case, I'll update our GPT code to fix some other issues (for example=
=20
the slice type is always set to 1).


For reference:

# newfs_msdos /dev/ad0s2=20
/dev/ad0s2: 185276 sectors in 46319 FAT16 clusters (2048 bytes/cluster)
bps=3D512 spc=3D4 res=3D1 nft=3D2 rde=3D512 mid=3D0xf8 spf=3D181 spt=3D63 h=

Observe carefully that the bsec of the newfs actually matches the number of=
=20
sectors of the third partition, with gpt index 2.
