1. cd /usr/src |
| 7 |
2. tar xjf /path/to/downloaded/kernel.tar.bz2 |
| 8 |
3. cd linux-new-kernel |
| 9 |
4. make mrproper |
| 10 |
5. cp ../path.to.old.kernel/.config ./.config |
| 11 |
6. make oldconfig |
| 12 |
|
| 13 |
7. make && make modules_install && cp .config /boot/config-new-version && cp |
| 14 |
System.map /boot/System.map-new-version && cp |
| 15 |
arch/i386/boot/bzImage /boot/vmlinuz-new-version && /bin/rm -f /usr/src/linux |
| 16 |
&& ln -s /usr/src/linux-new-kernel /usr/src/linux && vi /boot/grub/menu.lst |

A little terse, but yes. make oldconfig pulls in your existing .config file. |
| 19 |
It will prompt for new offerings not part of your old .config, usually the |
| 20 |
suggested default at the prompt is the way to go. |

When managing your own kernel, don't forget to a) install the modules (plus |
| 23 |
any other third party modules (i.e. nvidia driver modules) or your new kernel |
| 24 |
will give you grief, and b) recreate your /usr/src/linux symlink to point at |
| 25 |
the new kernel. |
| 26 |

Those steps above are the ones that I typically take (yes, folks will say to |
| 28 |
use "make install", but I'm still from the old school. |

The only part of the rote script above that I'm unsure about is the System.map |
| 31 |
stuff. I know it gets generated when the kernel is built, I know most |
| 32 |
systems have them in /boot, but for the life of me I never a) found out what |
| 33 |
it was for, b) found out if it had to be in /boot and if it had to be a |
| 34 |
special name (i.e. /boot/System.map explicitly), and c) why I even bother in |
| 35 |
the first place. |
