2. 설명
① Ubuntu 20.04를 기준으로 했다.
. 18.04도 가능할 것으로 보이지만, `startup.sh` 내용 中 마지막 라인에 있는
. `su` 또는 `runuser`의 `-w` 옵션이 18.04에서는 적용되지 않아서 지금은 20.04로 했다.
→ 18.04에서도 적용 가능하도록 연구해보겠다 (언제가 될지는...^^)
② 개발환경으로 사용되기에 기본적인 패키지들을 설치했다.
. 추후 필요에 따라 추가하면 된다.
. `DEBIAN_FRONTEND="noninteractive"` 부분이 없으면 설치 중간에 사용자 입력을 기다리기도 한다. (설치 오류)
