Just a couple of data points:

PARTX(8) PARTX(8)
NAME
partx - telling the kernel about presence and numbering of on-disk
partitions.
SYNOPSIS
partx [-a|-d|-l] [--type TYPE] [--nr M-N] [partition] disk
DESCRIPTION
Given a block device ( disk ) and a partition table type , try to parse
the partition table, and list the contents. Optionally add or remove partitions.
This is not an fdisk - adding and removing partitions is not a change
of
the disk, but just telling the kernel about presence and numbering of on-disk
partitions.

PARTPROBE(8) GNU Parted Manual PARTPROBE(8)
NAME
partprobe - inform the OS of partition table changes
SYNOPSIS
partprobe [-d] [-s] [devices...]
DESCRIPTION
partprobe is a program that informs the operating system kernel of
partition table changes, by requesting that the operating system re-read the
partition table.
------------
It seems they both do about the same thing. I'm not sure why we'd need both,
but I prefer adding it as it is a part of a package we are already installing.
