That's right -- it'll negotiate 9P2000.u if it can and otherwise drop back to 9P2000. I don't think it'll ever support 9P2000.l the very Linux-specific variant.

Is there any reason to support 9P2000.l if you're not Linux? Are there Linux-specific filesystem servers that won't negotiate plain 9P2000?
