其中有很多是从原系统的/etc下拷贝过来修改的,如果你是一个具有中等以上水平的Linux爱好者,那么应该一看就明白了,当然,你也可以根据自己的需要修改这些文件。其中最重要的是fstab和inittab,busybox内建的init程序用到的inittab文件的语法和一般的不一样,不能直接把原系统/etc下inittab文件拷贝过来。可以把busybox-1.00目录下的示例文件拷贝过来修改用。具体请看busybox的文档。busybox的init也可以不用inittab。但是在我制作babyLinux过程中有一个非常奇怪的bug。所有/sbin下的busybox链接在做成压缩的根文件系统,解压后都不能正常运行,显示找不到该命令。只有当我在/bin下做这些链接时才能运行。具体原因还不太清除,所以你需要做下面的工作:
#cd /babyLinux/rootfs/sbin
#ls
chroot getty ifconfig losetup pivot_root reboot swapoff sysctl
fdisk halt init mkswap poweroff route swapon telnetd |
查看到sbin下有上述链接,转到bin下:
#cd /babyLinux/rootfs/bin |
重新做这些链接:
#ln -s busybox chroot
#ln -s busybox getty
#ln -s busybox ifconfig
… |
然后把sbin下的链接删除,以节省空间:
#rm -rf /babyLinux/rootfs/sbin/* |
再把原先inittab中所有的sbin改成bin ,Init.d下的文件:rcS。请确保这个文件是可执行的,否则请改成可执行的:
rcS的内容:
#! /bin/sh
mount -o remount,rw /
/bin/mount -a
>/etc/mtab

可以自己作相应的修改。
以上是babyLinux根文件系统的所有内容,他的总大小应该在1M左右。
我还计划做一个live CD,但是目前已经有很多live CD了,而且都做的非常好。但是我会自己做一个作为学习Linux的一种手段。如果有时间,可能写一个做U盘Linux和live CD的教程。但是,我想不会写的和这个文档一样详细了,我的时间有限。可能大概讲一下原理和步骤。有经验的Linux爱好者应该可以通过阅读文档完成制作。
