    usr.sbin/crunch/crunchgen crunchgen.1 crunchgen.c 
  Log:
  Commands like gmirror, graid3, ... and others which use dlopen() to load
  classes from say, /lib/geom, cannot be statically linked completely.
  Moreover, those shared objects may require other shared objects (i.e.
   for geom, libraries like -lmd, -lcrypto).
  
  The libs_so extension to crunchgen fixes this by allowing some libraries
  to be linked in dynamically.  This requires that a copy of rtld and the
  shared libraries be made available to the crunched binary, and so is not
  suitable for all environments.  Crunchgen configurations which do not
  use the 'libs_so' keyword are unaffected and produce identical binaries
  with and without this commit.
