I am grateful for the opportunity to read other's views on these things.
So thanks to everyone for getting involved.
I would like to use my single user desktop as an example for a moment.
Sometimes a family member will use my PC.
I see nothing at all dangerous or otherwise undesirable in allowing that user by default the privilege of managing their removable devices.
For instance if they insert a DVD RW or a DVD RAM disk they have the opportunity to do with it as they wish ..... or should have if they do not, IMO.
The same applies to any other removable media they choose to insert.
All of course on the understanding that they cannot interfere with fixed storage devices, by default.
I guess I am back to the first wording of my question ...... what is there about allowing a user to manage their own devices that you disagree with?
Why should a user not be allowed to create, delete, make filesystem, label, check filesystem and so on, on devices which they have responsibility for?
Provided of course that there is no leaking of such powers to other devices which would be rightfully under root privilege.
I am approaching this from the device "ownership" point of view ........ almost like "its my PC and I decide what it does" ....... the removable devices are not owned by the OS/root ..... they are owned by the user who inserts them ....
I would be grateful if you would expand a bit on your reasons why you would prevent users from accessing their own devices.
If we have to go to an admin for permission, then we're already in a controlled environment, which by definition implies there are (or maybe should be) restrictions on what the end user can and cannot do. My opinion is that manipulating devices at their most base level falls squarely in this arena.
