This is the easy way: |
| 25 |
|
| 26 |
1) Back up user data (e.g. home directories) and system config files |
| 27 |
(e.g. /etc/) |
| 28 |
|
| 29 |
2) Install from scratch |
| 30 |
|
| 31 |
3) restore user data and config files. |

It's not just the kernel. If you want to avoid the 32-bit time |
| 41 |
problem, then you need to re-install all of the user-space librairies |
| 42 |
and binary exectuables that use the time() libc function. |
