詭異的 sudo

今天更新 Ubuntu apt 後，發現一件相當詭異的事情：

$ sudo su
>>> sudoers file: syntax error, line 2 <<<
>>> sudoers file: syntax error, line 16 <<<
>>> sudoers file: syntax error, line 17 <<<
>>> sudoers file: syntax error, line 17 <<<
>>> sudoers file: syntax error, line 18 <<<
sudo: parse error in /etc/sudoers near line 2

那把 /etc/sudoers 印出來看看：

# cat /etc/sudoers 
# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults

Defaults	!lecture,tty_tickets,!fqdn

# User privilege specification
root	ALL=(ALL) ALL
jserv	ALL=(ALL) ALL

奇怪，用 sudo 好幾年，還是第一次發生這種怪事，似乎是不吃 '#' 當作註解，真詭異！
