Comment:
This actually prevents screen from running at all:
```
$ screen
Cannot make directory '/run/screens': Permission denied
```

Ideas:
- Maybe some init script should `mkdir -m 1777 /run/screens` at startup?
- Maybe removing `--with-socket-dir=/run/screens` would use an alternative default which works for all users?
