I was thinking that it might be advantageous to have a user with permissions higher than the root user.
You see, I would like to keep all of the activities and almost all existing root user privileges exactly as they are now.
However, I would like the ability to deny privileges to root on an extremely isolated case by case basis.
One of the advantages of this would allow me to prevent certain unwanted files from being installed during updates. This is just an example of one possible advantage.
Because apt-get updates are run by root or with sudo privileges, apt-get has the ability to replace certain unwanted files during updates.
If I could deny these privileges to these individual particular files, I could set them as a simlink to
/dev/null or possibly have a blank placeholder file that could have permissions that would deny the file from being replaced during the update.
Additionally, I can't help but be reminded about a line which was said in an interview with one of the Ubuntu creators when the guy said something about how users better trust "us" (referring to the Ubuntu devs) "because we have root" which was a reference to how system updates are performed with root permission.
Simply altering the installation procedure to say work around this problem is absolutely not what I am interested here. Now that my mind has a taste for the idea of having the power to deny root access, I would like to figure out a way to make this happen just for the sake of doing it.
I just thought about this and have not spent any time on the idea so far and I'm fairly confident that this could be figured out. However, I am curious to know if this has already been done or if this is possibly not a new idea or concept.
Basically, it seems like there should be some way to have a super super-user which would have permission beyond that of the system by only one degree.
Note: Although I feel the accepted answer fits the criteria the most, I really like the answer by @CR. also.
I would like to create an actual user higher on the tree (me) but I guess I'll just have to sit down one day when I have the time to figure it out.
Additionally, I'm not trying to pick on Ubuntu here; I wouldn't use it as my main distro if I felt negative about it.
