| 3 # ulimit.hack: Create an intermediate program for use in | |
| 4 # between kernel initialization and init startup. | |
| 5 # This is needed on a 3b system if the standard CDLIMIT is | |
| 6 # so small that the dumped Emacs file cannot be written. | |
| 7 # This program causes everyone to get a bigger CDLIMIT value | |
| 8 # so that the dumped Emacs can be written out. | |
| 9 # | |
| 10 # Users of V.3.1 and later should not use this; see etc/MACHINES | |
| 11 # and reconfig your kernel's CDLIMIT parameter instead. | |
| 12 # | |
| 13 # Caveat: Heaven help you if you screw this up. This puts | |
| 14 # a new program in as /etc/init, which then execs the real init. | |
| 15 # | |
