I need to call `systemctl start myservice` near the end of a Bash script, but I really don't care about whether it will be successful or when it intends to return. I just need to start the action. It's others' task to monitor the status of that service. My script should return as quickly as possible, no matter whether that service has completed starting, I'm not depending on that.

My first thought was to use something like this:

```
# do other work
systemctl start myservice &
echo "done"
# end of script

```

But I've read that this is problematic with signals or in non-interactive environments, where my script is usually called. So I read on and found the `nohup` command, but that seems to write output files anywhere and might hang if you don't redirect stdin from /dev/null, they say.

So I still don't know how to do this correctly. I'm open for a generic way to start-and-forget any process from a Bash script, or for `systemctl` specifically as this will be my only use case for now.
