Please excuse the frivolity of this pull request. Without a public issue tracker, this was the only way I could send you a message.

I have written (for a class) a network stack in Rust, with the intention of adding it to an exokernel in Rust someday. You have the most actively-developed exokernel and, if the commit history is any indication, are currently adding networking support to it.

I would need to get permission from the Professor and my assignment partner to open source it, as it is a school assignment. But other than that I could start working on integrating the two in about a month, as that is when school gets out.

Hi everyone,

I'm new here, and just trying to compile, and it appears there's an issue with lazy-static.rs using the instructions as-is.

Here's my log replicating this issue:

Can anyone help me get this working?

Thanks, Charles

Other language-based operating systems, which are based on e.g. JVM or CLR, get away with not having CPU-level user mode or memory protection by having a virtual machine, which is known to take safety precautions (including verifying safety of the user-mode executable bytecode).

But Rust is compiled to native code. rustc invoked on RustOS will probably also just generate x86 (or whatever target architecture) code. How do you plan to distinguish between Rust-compiled, safe (I bet you plan to ban the unsafe keyword) binaries and some malicious code that one may put together using assembly or C or whatever and put on a RustOS machine?

Or are you planning to take some form of bytecode and compile upon exec() (or equivalent)?

when I $make iso, there is a compile error. my rustc version is too new?
