Hmm... my email server's seem to be getting flaky... I never received |
| 43 |
Sebastian's... |

Anyways, back to topic: I experiment a lot with the kernels, so I timestamp |
| 46 |
them all, and my grub menu lists all kernels found in /boot, complete with |
| 47 |
their respective timestamps. That way,if a .config change I did on K-1 |
| 48 |
(current is K-0, K-1 is the one before current) only now proved to be |
| 49 |
flaky, I can 'roll back' to K-2 or earlier. |
