Before merging the PR, comments starting with 
- ❌ ❓**must** be fixed
- 🤔 💅 **should** be fixed
- 💭 **may** be fixed

   The new KMS-based approach can use a key derivation function that is orders of magnitudes
   cheaper w.r.t. memory and CPU.
- Root credentials can now be changed easily. Before, a two-step process was required to
   change the cluster root credentials since they were used to en/decrypt the IAM data.
   So, both - the old and new credentials - had to be present at the same time during a rotation

## Advanced options

### Change default FTP port

Default port '8021' can be changed via

```
--ftp="address=:3021"
```

### Change FTP passive port range

By default FTP requests OS to give a free port automatically, however you may want to restrict
