11 years later, we (Timing Solutions, now a division of Microchip) are
still using SBCs with rl(4) hardware and still shipping software
updates with that driver built into the kernel. We build systems with a
lifespan in the field of 20 years or more, and the stability and
compatibility across OS upgrades over that kind of span is a BIG reason
to use freebsd rather than linux for such things.
