just executes `ps` directly.

```shell
$ docker run -it --rm alpine:edge su postgres -c 'ps aux'
$ docker run -it --rm alpine:3.7 su postgres -c 'ps aux'
PID USER TIME COMMAND
1 postgres 0:00 ash -c ps aux
12 postgres 0:00 ps aux
$ docker run -it --rm -v $PWD/su-exec:/sbin/su-exec:ro alpine:edge su-exec postgres ps aux
$ docker run -it --rm -v $PWD/su-exec:/sbin/su-exec:ro alpine:3.7 su-exec postgres ps aux
PID USER TIME COMMAND
1 postgres 0:00 ps aux
```

`su-exec` is no longer needed on Alpine 3.8+, `su` will execute the program
directly. It is however still useful on Debian 12 and probably other distros.

## Why reinvent gosu?

This does more or less exactly the same thing as [gosu](https://github.com/tianon/gosu)
but it is only 10kb instead of 1.8MB.
