置き換え その７

置き換え用 FLORA 350

カーネル再構築の 準備

簡単に済ませましょう

sv:/var/log# mount /dev/hda10 /mnt/
sv:/var/log# df

/dev/hda10            20641788   2576652  17016496  14% /mnt

.config の コピーです。

sv:/var/log# cd /mnt/usr/src/linux-2.4.31/
# ls -al | grep config
-rw-r--r--    1 root     root        27202 May 31  2008 .config

# mv .config 20080531_flora-370.config
sv:/mnt/usr/src/linux-2.4.31# cp /usr/src/linux-2.4.31/.config .config
sv:/mnt/usr/src/linux-2.4.31# cd

chroot で カーネル再構築

参考までに

Root device is (3, 10) ;;; IDE hda10

# less /usr/src/linux-2.4.31/Documentation/devices.txt 
...
  3 char    
...
    block       First MFM, RLL and IDE hard disk/CD-ROM interface
                  0 = /dev/hda          Master: whole disk (or CD-ROM)
                 64 = /dev/hdb          Slave: whole disk (or CD-ROM)

                For partitions, add to the whole disk device number:
                  0 = /dev/hd?          Whole disk
                  1 = /dev/hd?1         First partition
                  2 = /dev/hd?2         Second partition
...

vmlinuz 等の 入れ換え

sv:/usr/src/linux-2.4.31# cd /
sv:/# mv vmlinuz-2.4.31 20080531_flora-370-vmlinuz-2.4.31 
sv:/# cp /usr/src/linux-2.4.31/arch/i386/boot/bzImage vmlinuz-2.4.31
sv:/# cd /boot/
sv:/boot# mv System.map-2.4.31 20080531_flora370-System.map-2.4.31
sv:/boot# cp /usr/src/linux-2.4.31/System.map System.map-2.4.31
sv:/boot# ls /lib/modules/
2.4.31-plamo/           20080525_2.4.31-plamo/            org_2.4.31-plamo/
20070824_2.4.31-plamo/  20080531_flora-370_2.4.31-plamo/
sv:/boot# exit
exit

まあ もうあと少しで という所です。

にゃんたろう 拝！
