# 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.
