利用BusyBox定制Linux Live CD

for the match on that, which tells me I need "22 block 0" for the mknod command. To get this mounted, all the commands are listed here below.

    # mkdir /cdrom
    # mknod -m 600 /dev/hdc b 22 0
    # mount -t iso9660 -r /dev/hdc /cdrom

(f.2) What are all the steps needed for Unionfs?

You should download and burn http://prdownloads.sourceforge.net/souptonuts/cdrom_linux_boot_unionfs.iso

After you boot from the cd, issue the following command to load the unionfs kernel module.

   # insmod /unionfs/unionfs.ko

Now assuming you have an "ext3" filesystem on "/dev/hda2", mount it

   # mkdir /h
   # mount -t ext3 /dev/hda2 /h

Assuming the above filesystem has "/h/etc", "/h/bin", "/h/lib" and "/h/usr" these directories can be union mounted on top of "/etc","/bin", "/lib" and "/usr" as follows:

   # mount -t unionfs -o dirs=/etc:/h/etc=ro none /etc
   # mount -t unionfs -o dirs=/bin:/h/bin=ro none /bin
   # mount -t unionfs -o dirs=/lib:/h/lib=ro none /lib
   # mount -t unionfs -o dirs=/usr:/h/usr=ro none /usr
 

So what does this do? Well, now you can use gcc, emacs and a lot of the applications on the hard drive.

(f.3) How do I create the compressed initrd.bin file?

This is done in the script createiso.
