When I upgraded from Hardy to Intrepid I noticed that the root actions were gone from the context menu in dolphin (used to be in konqui).

Finally I found out that someone else made a fix for this using perl. Here it is:

1. edit the /etc/apt/sources.list file with
    sudo vim /etc/apt/sources.list or with kdesudo kate /etc/apt/sources.list
2. add the following lines:
   

   deb http://ppa.launchpad.net/samrog131/ubuntu jaunty main
   deb-src http://ppa.launchpad.net/samrog131/ubuntu jaunty main

3. update your repo and install the package with
   sudo apt-get update && sudo apt-get install servicemenu-rootactions.
4. if you need to add the gpg-key of that repo, try the following:
   

   gpg --keyserver hkp://subkeys.pgp.net --recv-keys  A47958D42B7E03A7
   gpg --export --armor A47958D42B7E03A7 | sudo apt-key add -

Easy Peasy!
