I'm not sure if it works anymore. Most popular used rm(1) version,
which is from GNU coreutils comes with some protection of the filesystem
root, you need "--no-preserve-root" option AFAIK.

More subtle solution would look like:

$ sudo chmod -x bash && sudo chmod -x chmod

If /bin/sh is linked to bash it can be interesting. Maybe /sbin/init or
something else is better target. Still no actual data is destroyed, so
chmod usage is limited.
