IIRC, Stanford University Networks built a lovely BSD-style system, then
decided to turn all pointy-haired and bought a UNIX license from AT&T.

I like Digital Unix too.  FWIW, it wasn't until version 5.0 that shutdown
actually used the rc.? directories; while they did indeed exist, they
weren't used.  Startup looked like SYSV, shutdown was pure BSD.  Oh, and I
found it an excellent CD burning platform, and I like not having to pay
extra just to get a supported C compiler.  That's my favourite Sun hate.
