        Sorry, the version of rm i've used honored the '-f' flag...
Playing mommy to users -- that's what you'd expect  from a university version
of unix.

You call programs that play mommy the norm?

        Things can be easily mounted and cross mounted under linux.  But
I didn't wanto to rm everything, I was using rmdir to remove empty directories.

I tried to use rmdir in a recusive form like the only supported recursive
version of rm -- one that uses wildcards.


You can't play mommie with 'rm' and expect people not to use such behaviors with
other commands.   If you are going to treat people like children to protect them
from themselves, then don't be surprised when they blame you for your
inadequacies.  You can't have it both ways -- the moral superiority of thinking
you are protecting people, yet the complete irresponsibility when the 
consequences
of teaching unthinking ways comes back to haunt you.

I regularly clean out directories.  It's rare that I will have mounted something
there.  But I've had the rm follow links it didn't understand on other OS's that 
were
not unix, but tried to be posix compatible -- and follow them into a recycle 
bin, where it
found pointers to a whole bunch of places on the file system.

        Is that why almost all unix command have options to prevent them
from doing just that... and not it is not weird.  Only under BSD is it weird, 
but
elsewhere, people mount things all over the place.

        People are being encouraged in some circles to use mounts over a 
softlink --

        I don't have anything mounted under my /tmp, but I could easily see a
dir there being used as a scratch dir or a place to mount a scratch volume 
temporarily.

        If someone runs a program that does such a delete using BSD crippled 
utils
that cause bad behaviors, telling them they are weird  as a response is perfect 
for
someone who thinks the world revolves around them and anyone who does anything 
differently
is 'weird'....

        That's really special.
