I think it's still "common practice" to "taste"
the device file in order to make new partitions
show up:

	# true > /dev/da0

In this example, I assume that da0 is the _disk_
in question where you've added partitions. Now
the proper device files (e. g. /dev/da0a, /dev/da0d,
/dev/da0e, /dev/da0f... resp. /dev/da0s1a, /dev/da0s1d,
/dev/da0s1e, /dev/da0s1f...) should appear in
the device file system.
