linux-source-2.6.20.1i586.tgz を持ってきて、ipv6をモジュールで使うようにしたが、起動カーネルは/boot/vmlinux.gzまたは/boot/vmlinux.bz2でなければならないのに、make installだと/boot/vmlinuzになるので、起動できない。 それなら、と、

# cd /boot
# ln -sf vmlinuz vmlinux.gz

としてみたが、やはり起動できない。なんでか。

裏面のスイッチをOff/Onするしかなくなる。

Once you've configured your kernel, issue the following commands:

Code:

# make vmlinux modules modules_install
# strip vmlinux
# bzip2 vmlinux
# cp vmlinux.bz2 /boot/

And be sure to double check the size of /boot/vmlinux.bz2.  It needs to be less than 1800KB. 

bfnでネットブートしてからローカルディスクをマウントし、コンパイル済のvmlinuxをbzip2で圧縮、/bootにコピーすると、bfdで起動でき、ipv6も有効になった。
