A very important advice. Labels make it easier to recognize the
purpose of partitions by name (instead of number), and they also
"survive" if a disk gets moved from system to system.

Even on single-disk systems, device names might change due to a
system update: A disk that has been known as ad4 could come up
as ada0 after an improved "controller" has been introduced to
the kernel. :-)

And it saves you a lot of trouble getting "drivers" for hardware
that has been considered "outdated" and isn't supported anymore
by "Windows" or by its manufacturer.
