Samba has a configuration parameter that allows you to set an arbitrary 
command as a "panic action" script.  This can then be used to gather 
debugging information or prepare a bug report (see other thread).  This 
also has the added flexibility that binary packagers can add extra 
information specific to their environment.  It may be worthwhile to 
research whether we could do something similar.
