2005-03-17: 早起きはkernel再構築

今日は早起きしたので積み残していたGENTOO Linuxのカーネルバージョンアップを始めてしまいました。

linux-2.4.28-gentoo-r8がダウンロードしてあったのでこんな感じに。
スーパーユーザになって
cd /usr/src
rm linux
ln -s /usr/src/linux-2.4.28-gentoo-r8 linux
cd 前のカーネルソースの.config linux/new.config
cd linux
genkernel --menuconfig all

(menuconfigが現れたらnew.configをLoadし終了)

＊ Gentoo Linux Genkernel; Version 3.1.1b
＊ Compiling Linux Kernel 2.4.28-gentoo-r8 for x86...

＊ kernel: >> Running mrproper...
＊ config: Using config from /usr/share/genkernel/x86/kernel-config-2.4
＊ Previous config backed up to .config.bak
＊ >> Running oldconfig...
＊ kernel: >> Cleaning...
＊ config: >> Invoking menuconfig...
Using defaults found in .config
Preparing scripts: functions, parsing............................................................................................done.

Saving your kernel configuration...

＊＊＊ End of Linux kernel configuration.
＊＊＊ Check the top-level Makefile for additional configuration.
＊＊＊ Next, you must run 'make dep'.

＊ kernel: >> Making dependencies...
＊ >> Compiling 2.4.28-gentoo-r8 bzImage...
＊ >> Compiling 2.4.28-gentoo-r8 modules...

こんな感じでmoduleのコンパイルを行っているようす。これが時間がかかります。つづきは後で！

＊ Copying config for successful build to /etc/kernels/kernel-config-x86-2.4.28-gentoo-r8
＊ initrd: >> Initializing...
＊ >> Copying modules...
＊ >> Copying auxilary files...
＊ :: Size is at 4378K
＊ >> Creating loopback filesystem...
＊ >> Moving initrd files to the loopback...
＊ >> Cleaning up and compressing the initrd...
＊ >> Installing bootsplash [ using the gentoo theme ]...
＊
＊ Kernel compiled successfully!
＊
＊ Required Kernel Parameters:
＊ root=/dev/ram0 real_root=/dev/$ROOT init=/linuxrc
＊ ramdisk_size=8192
＊ [ And "vga=0x317 splash=verbose" if you use a framebuffer ]
＊
＊ Where $ROOT is the device node for your root partition as the
＊ one specified in /etc/fstab
＊
＊ If you require Genkernel's hardware detection features; you MUST
＊ tell your bootloader to use the provided initrd file. Otherwise;
＊ substitute the root argument for the real_root argument if you are
＊ not planning to use the initrd...
＊
＊ Do NOT report kernel bugs as genkernel bugs unless your bug
＊ is about the default genkernel configuration...
＊
＊ Make sure you have the latest genkernel before reporting bugs.

それで7時ぐらいに終了。約１時間くらいかかりました。つつきは後で！

vi /boot/grub/menu.lst

でgrubを修正(新しいカーネルを追加)

emerge alsa

これも忘れず行って再起動！
