It’s unfortunate that SKAS0 mode is poorly documented on the User-Mode Linux (UML) web site. For example, this page about SKAS doesn’t mention it. It is explained in Jeff Dike’s UML book though.
I wish they would update the UML web site as it gives the impression that TT and SKAS3 are the only choices, which is no longer true, as SKAS0 was added to the kernel in version 2.6.13.
Here are a handful of resources that I found that describe SKAS0:

I gotta admit, I didn’t even know about SKAS0 mode, but I can’t see why I’d care much. It is interesting from a technical perspective, but from a functional perspective you’d think you’d either want to got with tt or SKAS3. Maybe that’s just me.
Yeah I would think people who are using UML pretty seriously would want SKAS3 anyway, but it’s nice to know that even without patching your host kernel, you get SKAS0, which is not that bad, since TT is pretty well bashed on the UML web site. Good point though. SKAS3 is still the way to go.
