+## handle download failure and check dir besides /lkp and /opt

+original:

• curl_cmd: %x(curl -sS --create-dirs -o #{path}/#{name} #{url} && gzip -dc #{path}/#{name} | cpio -idu -D #{path})
• download cgz file and unpack it in one line

+improvement:

• curl_cmd: split download cgz file, check dir and unpack the cgz file into standalone lines.
• system('wget -t 3 -T 20 -O #{path}/#{name} #{url} 2> /dev/null')

•  use system to call the linux command, it will retusn true/false
  

•    - true: execute success
  

• • false: execute in failure

•  raise error if download in failure
  

• %x(gzip -dc path/cgz_file | cpio -idt)

•  use %x(command) can get the output of the command, extract the file list of the cgz file
  

•  check files from the file list and check if the file/dir is besides the /lkp or /opt
  

•  if no files/dirs besides /lkp or /opt
  

•    %x(gzip -dc path/cgz_file | cpio -idu -D path)
  

•  if exist files/dirs besides /lkp or /opt
  

•    save the cgz to opt
  

• unpack the cgz file in container

•  ---
  

•  maybe can ignore check the cgz file if it containers files/dirs besides /lkp or /opt
  

•  just unpack all the cgz file in the container
