A little of both, actually. Depends what meaningful means.

I'm aware that kernel level stuff is somewhat different; and a lot more people seem to hate Linux for kernel details than BSD, which probably says something about which is worse. Personally, I'd heard more of that to do with SCSI than networking, but I don't think it's isolated.

In userland (which is where I live), however, isn't it pretty near true? (It is AFAICT; not running a BSD system, but continually running against BSD-centric directions, man pages, etc. in online searches.) Don't know if scumgrief anticipates doing much kernel stuff, anyway...
