f9: why does rc.local not run?

[sean darcy]

I've noticed that rc.local doesn't run on boot anymore.

initscripts-8.70-1.i386

cat /etc/rc.d/rc.local

  #!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

hal-disable-polling --device /dev/scd0

echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

/usr/sbin/safe_asterisk

echo rc.local_worked


This works OK just being executed directly ( ./rc.d/rc.local), but it 
doesn't get run on boot. asterisk doesn't start up. And:

cat /proc/sys/vm/dirty_writeback_centisecs
499

So why is rc.local not getting run on boot?
