common is an Ansible role used to

• change default shell from dash to bash \
  • dash is set by default and need to change it to bash shell
• change umask default permission from 022 to 027
  • The default umask on Ubuntu is 022 which means that newly created files are readable by everyone, but only writable by the owner and group if USERGROUPS_ENAB: "yes" in /etc/login.defs
  • to better protect the directories and files, we will set the umask to remove all permissions for others and remove write permission for groups.
  • afterwards, the permission of directory is 750 and the permission of file is 640.
• others ...

Running Ansible in a virtual environment allows for a lot of testing flexibility.
