How about replacing both paragraphs with
major, minor
Historically, a device number consisted of two parts: the major
number, which identified a device driver, and the minor number, which
identified an individual device handled by that driver. FreeBSD no
longer makes that distinction; each device has a unique system-wide
minor number, and the major number is always zero. However, the
distinction is still important when creating device nodes on a file
system intended for use by an older system.
(modulo errors in grammar and style)
The paragraph about b | c should be altered in a similar manner, to
emphasize that FreeBSD does not have block devices, but that block
device nodes can still be created for use by older systems.
