I would like to suggest that a regularily updated file be maintained of   
DDEBs (DON'Ts, DON'T EVERs, and BEWAREs); e.g.,                           
an annotated list of things NOT TO DO with linux or which may be hazardous
to the health of a linux usr; e.g.,                                       
        DON'T EVER:                                                       
        - arbitrarily delete files [you may make your system unusable]    
        - use an OLD boot-image with a more recent root-image             
                [e.g. boot-image-95 with root-image-96]                  
        BEWARE:                                                           
        - of updating binaries before testing them [give them a new name] 
        - of compiling your own binaries IF you don't have sufficient     
          memory/swap space                                               
        DON'T use rm [ write an alias 'rmi=rm -i '] (even a typo rm - i * 
        can produce a surprise)                                           
        etc.                                                              
This is just a starter; pls send candidates for DDEBs to me; I'll collate 
them, summarize them, and post them for comments.
