This is along the same lines as Message #34 at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=751892 > To random people reading this bug: please do not EVER do > this or it may subtly break other things and then get you > flamed when you will waste my time debugging that. Although the issue is treated sympathetically towards the end of the report, I don't believe I've ever seen an example of subtle breakage. I agree with what is said in Message #23 at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=788662 > In any case, it seems unfortunate that users can no > longer write an image to a USB disk without using root. > Especially because that makes it easier to make a mistake > and overwrite the wrong disk.

Which is why I have a udev rule with SUBSYSTEM=="block", ATTRS{removable}=="1", GROUP="floppy" in it. I might stop doing that if its use was demonstrated to have an adverse effect on other things I do. -- Brian.
