Passwordless automount under regular user

[Антон Плескановский <pleskan87@gmail.com>]

Good Morning dear Debian GNU/Linux users!

I've got a question for you: What's the reason I need to create following automount rule for polkit

in order to mount disk partitions without a password from any GUI filemanager?

[Allow Unauthorized mounting/Unmounting]
Identity=unix-group:plugdev;cdrom
Action=""
ResultAny=yes
ResultInactive=yes
ResultActive=yes

 Is this intended behaviour and what is the case for doing this?

  Why don't  maintainers set this up by default in Debian?

  Ubuntu and its derivatives have the feature has been enabled.

 So, would you like to explain the matters to me?
