Could people have a look at standards instead of trolling?
SUSv4 adds the following exception:
« if an operand resolves to the root directory, rm shall write a
diagnostic message to standard error and do nothing more with such
operands. »

rm does not preserve root by default
Respectfully, I think your argument in this paragraph is a logical fallacy,
along the lines of a Slippery Slope argument.
There is no slippery slope, no string of events, just one event
causing another, a precedent set.

Just to prove to experienced users that --preserve-root by default is a benefit:
I consider myself a seasoned Linux user. Been using Linux for more than a
decade. I recently toasted a filesystem with rm -rf /. What I actually typed
though was something like:
f=/path/to/somedir rm -rf $f/ ;

But that would mean that every new user would have to add that to bashrc

So, what's next? Patch dd to prevent it from wiping your partition?
There are infinite ways to wipe your root file system. There is little
value in adding a safety here, while a slight variation of the theme

@Dr Small - I'm suggesting this change would be made in the default

This way:
1. novice users are protected by default
2. anyone who really wants to delete / can use --no-preserve-root attribute
3. people who prefer the
Also, this prevent typeo by root:

The space after slash really makes a different.
Also there is no confirmation for 'rm -rf /'.
So turn on protection is much safer.

There should at the very least be a warning with a yes/no prompt and
then have the user type in the root password one more time to finalize
it. This at least prevents anything rash from happening. As mackial
stated, more typing may be a good thing in this instance.

I can confirm this behavior. Other distros have taken steps to protect
unknowing users from wiping their root directory, and it seems as if it
