这是我linuxrc中的挂载cdrom的内容，我用的的busybox的mdev，不成功,找不到原因

1. 
   
2. #!/bin/sh
   
3. export PATH=/sbin:/bin:/usr/sbin:/usr/bin
   
4. 
   
5. echo "mounting proc filesystem"
   
6. mount proc proc -t proc
   
7. echo 0x100 > /proc/sys/kernel/real-root-dev
   
8. echo "mounted proc"
   
9. 
   
10. echo "mounting sys filesystem"
    
11. mount -t tmpfs mdev /dev
    
12. mount sysfs /sys -t sysfs
    
13. echo "mounted sys"
    
14. 
    
15. /bin/mknod /dev/console c 5 1
    
16. /bin/mknod /dev/ram0 b 1 0
    
17. /bin/mknod /dev/null c 1 3
    
18. /bin/mknod /dev/tty0 c 4 0
    
19. /bin/mknod /dev/tty1 c 4 1
    
20. /bin/mknod /dev/tty2 c 4 2
    
21. /bin/mknod /dev/tty3 c 4 3
    
22. 
    
23. echo "starting mdev"
    
24. /bin/echo /sbin/mdev > /proc/sys/kernel/hotplug
    
25. mdev -s
    
26. echo "started mdev"
    
27. 
    
28. echo "mount cd/dvd"
    
29. 
    
30. for i in /dev/hd*
    
31. do
    
32.   if [ -b ${i} ] && [ ! -b ${i}1 ]
    
33.       then
    
34.       /bin/mount ${i} /cdrom -t iso9660
    
35.       if [ $? -eq 0 ]
    
36.           then
    
37.           /bin/echo "Had found CD/DVD drive at $i......"
    
38.       fi
    
39.   fi
    
40. done
    

复制代码

/bin/echo "Had found CD/DVD drive at $i......"  没有执行


我在下面加了/bin/sh/开了个shell,然后ls /dev下面有了一些设备,可是没有hd*
