Static keyword for creating buffers in data

Explain
1 
fn execSys() void {
    var path_buff: [MAX_PATH]u8 = undefined;
    const proc = Process.currentOrPanic();
    const path_user_address = proc.trapframe.?.a0;
    proc.pagetable.?.copyFrom(path_user_address, @ptrCast(&path_buff), MAX_PATH) catch |e| {
        lib.printErr(e);
        lib.kpanic("Failed to copy path from user to kernel");
    };

    exec(@ptrCast(&path_buff)) catch |e| {
        lib.printErr(e);
        lib.kpanic("Failed to exec /init");
    };
}

I currently have to globally define it and add the function name to the var name
I get errors with stack when defining path buff locally. is there no way to add a static tag to this variable, instead of using a struct definition? it doesn’t really make sense and isn’t that readable.

You can find an example of static lifetime variables in Static Local Variables
