Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

KT olleh ucloud biz 서버를 구매하면 기본으로 root 계정을 사용하게끔 되어 있는 것 같다.

add new adminsudo user

root@xxx:~$ useradd <username> -m -s /bin/bash
root@xxx:~$ passwd <username>
Retype new password:
passwd: password updated successfully
root@xxx:~$ adduser <username> sudo
Adding user `<username>' to group 'sudo' ...
Adding user <username> to group sudo

disable root account

username@host:~$ sudo passwd -l root
passwd: password expiry information changed.
