debian/ubuntu 的 update-alternatives 指令
- install gcc-2.95, gcc-3.4
- update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-3.3 52
- update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-2.95 53
- update-alternatives --config gcc
Debian-Kernel-Compile-Howto (Kernel 2.6)
- apt-get build-dep linux-headers-`uname -r`;
- apt-get install kernel-package ncurses-dev fakeroot wget bzip2 module-init-tools procps initrd-tools
Use "initramfs-tools" instead of "initrd-tools" on Squeeze(6.0). - download, uncompress, and config linux kernel source somewhere, e.g. /usr/src
- make-kpkg clean
- fakeroot make-kpkg --revision=custom.1.0 linux-image
fakeroot make-kpkg --revision=custom.1.0 linux-image -j4
CONCURRENCY_LEVEL=4 fakeroot make-kpkg --revision=custom.1.0 linux-image
開始build kernel,通常會很久,因為有很多module要build。build完後在上一層(linux-src/../)下會產出一個linux-image-2.6.8.1_custom.1.0_i386.deb - dpkg -i linux-image-2.6.8.1_custom.1.0_i386.deb
- Make initrd by
cd /boot/;mkinitrd -o /boot/initrd.img-2.6.8.1 2.6.8.1;
Use "mkinitramfs" instead of "mkinitrd" on Squeeze(6.0)cd /boot/;mkinitramfs -o /boot/initrd.img-3.2.0+ 3.2.0+;
- Grub, Edit /boot/grub/menu.lst, add the following line to the new item
initrd /boot/initrd.img-2.6.8.1
LILOinitrd=/boot/initrd.img-2.6.8.1
Or simply "update-grub"

- apt-get install kernel-package libncurses5-dev fakeroot wget bzip2
- download, uncompress, and config linux kernel source in /usr/src

Debian 2.6.24的linux-image不能開機
連linux-source-2.6.24按照上述程序也不能開機,似乎找不到initrd
2.6.18的就ok
ERROR: Documentation/lguest: No such file or directory
20120315 - linux-3.2.0 w/ Squeeze (6.0)
#638012 - error compiling(make: *** Documentation/lguest: No such file or directory. Stop) - Debian Bug report logs
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=638012
As a workaround simply linking the virtual/lguest/ directory from the Documentation folder of the source tree will solve the problem.cd ./Documentation
ln -s virtual/lguest/
