2. 
   
3. #!/bin/sh
   
4. #
   
5. # The purpose of the script is to install the bootloader on
   
6. # a usb key for Synology can be booted from usb key
   
7. #
   
8. #help screen
   
9. 
   
10. if  [ $# != 1 ]; then
    
11. echo "
    
12. standard use of script is:
    
13.     ./usb_inst.sh    the script will install bootloader on usb key, it will not
    
14.                      touch the partition tables and therefore please perserves data.
    
15. possible options are:
    
16.     /dev/sd*         usb key device name for Synology bootloader.
    
17. example
    
18.     ./usb_inst.sh /dev/sdc2
    
19. "
    
20. exit 1
    
21. fi
    
22. 
    
23. #check if the device exist
    
24. if [ ! -e $1 ]; then
    
25.     echo "$1 does not exist."
    
26.     exit 1
    
27. fi
    
28. 
    
29. if [ ! -x /mnt/grub ]; then
    
30.     echo "There is not correct bootloader installer"
    
31.     exit 1
    
32. fi
    
33. 
    
34. mount $1 /boot
    
35. if [ $? -ne 0 ]; then
    
36.     echo "The usb device could not mounted"
    
37.     exit 1
    
38. fi
    
39. 
    
40. cp -rf /mnt/boot /boot
    
41. tmp_disk=$(echo $1 | sed "s/\([0-9]\)//g")
    
42. grub-install --root-directory=/boot $tmp_disk
    
43. if [ $? -ne 0 ]; then
    
44.     echo "install usb device bootloader fail"
    
45.     umount /boot
    
46.     exit 1
    
47. fi
    
48. 
    
49. umount /boot
    
50. echo "Generate usb key bootloader successful"
    
51. exit 0

脚本文件在映像中，如果解压没有问题，是不可能损坏的。损坏了就会出现解压CRC校验错误。
