+ # ulimit.hack: Create an intermediate program for use in
+ # between kernel initialization and init startup.
+ # This is needed on a 3b system if the standard CDLIMIT is
+ # so small that the dumped Emacs file cannot be written.
+ # This program causes everyone to get a bigger CDLIMIT value
+ # so that the dumped Emacs can be written out.
+ #
+ # Users of V.3.1 and later should not use this; see etc/MACHINES
+ # and reconfig your kernel's CDLIMIT parameter instead.
+ #
+ # Caveat: Heaven help you if you screw this up.  This puts
+ # a new program in as /etc/init, which then execs the real init.
+ #
+ cat > ulimit.init.c << \EOF

+       /* 262,144 allows for 128Mb files to be written. */
+       /* If that value isn't suitable, roll your own.  */
+       execv("/etc/real.init", argv);

+ # Upon system reboot, all processes will inherit the new large ulimit.
