Well, working heavily with Solaris, BSD, Linux, AIX, SCO, HP-UX, and more I would say that what you learn in Linux will be at *least* as transferrable to the other OSs than what BSD will teach you. Solaris uses System V init, like Linux. BSD uses BSD init, like AIX (actually that should have been "AIX uses BSD init like BSD"). Either way you go (I suggest go both ways) your skills will cross the other platforms. In fact Linux and BSD use many of the same software packages so....
