When running Windows the user has the ability to change anything, even core system elements. A knowledgeable user can change any and every aspect of a windows operating system and file system. This is also true for curious children and unknowing adults, and none of it requires special privilege unless such privileges have been setup in advance.
By contrast, linux based OS's are built on a privilege access protocol. The problem with this protocol is the user is below root. An owner of a machine is routinely denied read/write access because of privilege.
If I had one complaint about linux OS's(just so happens I have only one), it is the system of privilege. As I see it, this is my machine. If I want to mess it up, let me. But I also understand that privilege is used for program and network security.
The fact that privilege is such a blanket protocol has left the advanced user(albeit not expert) rather frustrated.
If I could log on as root, and have consistent root access, while keeping things simple.....
Errrrrrrrrrrrr....
I want to open a .png file in gimp(can do). I want to modify this image(can do). I want to save my changes to the same file name and location(can not do). This file has root only write access.
