This function is used to request confirmation for doing an operation |

on a given list of instances. |

The inames argument is what the selection algorithm computed, and |

the text argument is the operation we should tell the user to |
|
| 110 |
confirm (e.g. 'shutdown' or 'startup'). |
|

Returns: boolean depending on user's confirmation. |
