That's since you've got the picture wrong IMHO. See it as:
. DOS slice (primary)
. FreeBSD slice, containing BSD-style partitions:
. /
. swap
. /usr
. extended slice # 1: Linux swap
. extended slice # 2: Linux /
Linux doesn't have partitions (in the BSD terminology), it always uses
the fdisk slices. To support the above with /dev nodes:
/dev/wd0 (entire disk)
/dev/wd0s1 DOS slice (primary)
/dev/wd0s2 FreeBSD slice, containing BSD-style partitions:
/dev/wd0s2c (same as /dev/wd0s2)
/dev/wd0s2a /
/dev/wd0s2b swap
/dev/wd0s2e /usr
/dev/wd0s3 (doesn't exist, empty fdisk slot)
/dev/wd0s4 (doesn't exist, empty fdisk slot)
/dev/wd0s5 extended slice # 1: Linux swap
/dev/wd0s6 extended slice # 2: Linux /
You can clearly see the nested slice/partition scheme of BSD, as
opposed to the single-level fdisk partitions.
The wd0s5 etc. /dev nodes are likely to not yet exist. You gotta run
MAKEDEV for them.
