Password less konquersu
 

I noticed that several distro's now do not require a password to open a directory as a super user. How I can do that to my system?

You should have read access to most directories on your system. Which ones can you not browse as a user?

Sorry, I was not clear in my question. I meant opening the directory for reading and writing not just for reading (granting write access for normal user to all system directories owned by root). I can read most of the directories in my system without a need for a password.
