隔离用户的时候出错

```go package main import ( "log" "os" "os/exec" "syscall" ) func main() { cmd := exec.Command("sh") cmd.SysProcAttr = &syscall.SysProcAttr{ Cloneflags: syscall.CLONE_NEWUTS | syscall.CLONE_NEWIPC | syscall.CLONE_NEWPID | syscall.CLONE_NEWNS | syscall.CLONE_NEWUSER, } cmd.SysProcAttr.Credential = &syscall.Credential{Uid: uint32(1), Gid: uint32(1)} cmd.Stdin = os.Stdin cmd.Stdout = os.Stdout cmd.Stderr = os.Stderr if err := cmd.Run(); err != nil { log.Fatal(err) } os.Exit(-1) } ``` 出现错误 2017/09/05 16:51:38 fork/exec /usr/bin/sh: invalid argument exit status 1
