#
# 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.
