# untrappable-signal

**Default severity:** `warning`

Unix-like kernels handle `SIGKILL` and `SIGSTOP` directly. They are never
delivered to the process, so registering them with `os/signal` cannot work.

## Bad

```go
signal.Notify(ch, os.Kill)
```

## Good

```go
signal.Notify(ch, syscall.SIGTERM)
```
