☆ lxcのcronでrootがsudo

centos7なかなか慣れず、試行錯誤。
タイトルの組み合わせが、なぜかうまく機能しなかった。
適当に検索して、パスワード指定忘れと /etc/sudoersの一行を塞いでようやく。

$ cat /etc/pam.d/crond 
#
# The PAM configuration file for the cron daemon
#
#
# No PAM authentication called, auth modules not needed
account    required   pam_access.so
account    include    password-auth
session    required   pam_loginuid.so
session    include    password-auth
auth       include    password-auth

$ sudo visudo
# Defaults specification
 
#
# Disable "ssh hostname sudo ", because it will 
# show the password in clear.
#     You have to run "ssh -t hostname sudo ".
#
#Defaults    requiretty

$ sudo vi /etc/crontab
# *  *  *  *  * user-name  command to be executed
