A filesystem undo is most needed on servers. There usually is no KDE.
However a trash can can be done with hard links and a cronjob. What I
would like to have is more - I think I was not clear enough about that.
I not only want to undo deletions. I would like to be able to undo all
file system operations. 

VMS has a versioning file system, which does about what I want. It feels
pretty good if you can undo "everything I did since 11:30".
