Error Message가 나오는데...
 Sorry, the host 'localhost.your.domain' could not be looked up.
Please configure the 'hostname' command to return a correct hostname.
If you want to solve this at a later stage, restart this script with
the --force option
 이렇게 나오네요...
hostname에 --force 옵션을 넣으라는 거 같은데...
그런 옵션 없는디요...-_-a
흠.....거참..-_-a
