We need unity in the field of security, so that users won’t panic on either platform if they see something like this, they will have seen it before and be reassured that they are in control etc.

If Linux does do something similar to UAC, which I think it should, it will most likely be accused of copying by the anti-Linux group. However, having something unified and recognisable across platforms and systems (like the feed icon idea) can only help users on all systems to feel safe and comfortable with the system they are using.

Peter and I had quite a heated debate on a forum about the merits of root in Linux. He is convinced that it is a good idea, adds significantly to the security of the OS and isn’t too much of an inconvenience.

I think that root is such a hindrance that it must be either removed from Linux or its implementation removed significantly. This is primarily because it involves opening a terminal. Whilst this is trivial for existing users of linux, the sort of user it wants to attract (computer-literate but not necessarily a geek) will not be happy with command lines, and so however simple the code is, the opening of the terminal in itself is a barrier.

The User Account Protection feature in Vista is much better than the root idea in linux. This is because it:
a) does not require any use of the command line
b) asks for permission from the user AFTER the application has requested the action, as opposed to having to log in as root before the action is requested
c) allows for seamless checking, in a clear manner, ensuring that the user understands what is happening, and does not panic.

Linux needs to adopt this approach, or a similar method of making root easier to use.
