 * 參考 /var/lib/dpkg/info/openssh-server.postinst
   * 加帳號的參考寫法
{{{
setup_sshd_user() {
        if ! getent passwd sshd >/dev/null; then
                adduser --quiet --system --no-create-home --home /var/run/sshd --shell /usr/sbin/nologin sshd
        fi
}
}}}
     * getent - get entries from administrative database
{{{
jazz@ubuntu:~$ getent passwd jazz
jazz:x:1000:1000:Jazz Yao-Tsung Wang,,,:/home/jazz:/bin/bash
jazz@ubuntu:~$ getent passwd hadoop
}}}
   * 設定預設 run-level 還有啟動服務的寫法
{{{
setup_init() {
        if [ -x /etc/init.d/ssh ]; then
                update-rc.d ssh start 16 2 3 4 5 . stop 84 1 . >/dev/null
                if [ -x /usr/sbin/invoke-rc.d ]; then
                        invoke-rc.d ssh restart
                else
                        /etc/init.d/ssh restart
