Ah, interesting, I'll have to dig into it more :) I've never used OpenBSD so I've just had to watch on the sidelines. Anywhere I can read more about this?

- jart 4y agoThe msyscall() man page. The Cosmopolitan Libc source code. In the cosmoverse, we produce static executables that run on six operating systems. The only Libc we use is obviously our own. So when our executables get loaded on OpenBSD, we do the same thing OpenBSD Libc does, which is calling msyscall() so that only a privileged subset of the application is able to use SYSCALL. In our static binary world, that's basically any function that uses the `privileged` keyword. It makes things a little dicey if we want to dynamically link OpenBSD Libc since we have to pull out some aggressive hacks like Xed in that case. But overall it's fine.
