The <option>--select-os</option> option switches to an |

interactive OS reinstall. The user is prompted to select the OS |
| 1254 | 1257 |
template from the list of available OS templates. |

be required to confirm this action, unless the |
|
| 1263 |
<option>-f</option> flag is passed. When multiple instances |
|
| 1264 |
are selected (either by passing multiple arguments or by |
|
| 1265 |
using the <option>--node</option>, |
|
| 1266 |
<option>--primary</option>, <option>--secondary</option> or |
|
| 1267 |
<option>--all</option> options), the user must pass both the |
|
| 1268 |
<option>--force</option> and |

<option>--force-multiple</option> options to skip the |
