    Blaisorblade> What's this?

  A tool which LD_PRELOAD's a library that intercepts all calls that
require root, and "emulates" them.
  I.e. if a program does "chown(2)", it just remembers that this
occured, and when a stat() is made, it returns the "right" answer.  
  (so tar/mkjffs, etc. get the right answer)

  Used in debian a lot.

    Blaisorblade> Yes, that's because it turns the console to raw mode (don't ask me why).
 
  Because, you'd like to have ^C get passed to the program being run
under the UML :-)
