Oh right, my bad x) I agree, it's a little bit akward to use su then cat everytime.

That could be possible but for the moment I didn't encouter any problem with cat. I think I'm going to stick with it for the time being.

Yep that's right, but I use fdisk to check my drives before writing on them and it also requires sudo...

My favorite way to create a boot media is simply to use cat. No arguments, no shenanigans just a cat into the device :

cat debian.iso > /dev/sda
