another trick is to create a file .%NO_RM% and %NO_RM%, the % char comes before pretty much any 
other printable character. Now chatter +i those two files, and if you do an rm -rf * .wibble or 
whatever, the first file that the shell attempts to rm, is immutable, and the rm halts, warning you. 

Not perfect, but a useful bit. This works with Bash, on Ext2/3, dunno
about other shells/filesystems.
