I am trying to understand this situation... Today I got a problem with de sudoers file since I modified and got problem whit this modification. So the only way to solve the problem was to modify the file using root in Recovery Mode.
And there is where the problem start.... no password was asked at all... so, just by choosing 2 options (Recovery Mode in Grub and Root in Recovery Mode), I've got access to all my system and all his files as a root.
This is very dangerous ! Anyone could easily erase important files or simply broke the entire system without any password/password/....
Is there any official communicate by Canonical about this ? It is simply an old forget feature or just something that no one want to change just because they don't want to ?
