I wouldn't doubt that distro's like ubuntu do and I know a lot of them set
it for rm. These options make it more ID10T friendly. and they should be
fairly easy to unset, all you have to do is figure out which file (like
bashrc or /etc/profile) is sourcing it as an alias and remove it. I have
quite a few aliases I set in my bashrc to make my life easier.
