Don't do that if you don't have some tool like KVM, or other remote |
| 24 |
management of the server. Or if it is available in the data center, |
| 25 |
just call them and order this service for the time you need to do |
| 26 |
updates. |

|

This is why I don't use gentoo on servers any more, just because |
| 29 |
I rather stay safe than sorry. |

But if you really need to do that (and you don't have any chance to |
| 32 |
get KVM attached), just create an virtual machine with backup of your |
| 33 |
server and test that kernel there, and check that you have all the |
| 34 |
modules you need on the server. But this is the last thing I would do. |

Good luck, |
