There isn't an /etc/rc.d/rc.0 . As for /etc/rc.d/ I tried looking
for anything that remounted the disks read only, and I didn't find anything.

It looks like FreeBSD might not follow that. Under /etc/rc.d
we have :
DAEMON dumpon kpasswdd ntpd securelevel
LOGIN early.sh ldconfig ntpdate sendmail
NETWORKING fsck local othermta serial
SERVERS gbde localpkg pccard sppp
abi gbde_swap lpd pcvt sshd
accounting hostname mixer pf swap1
addswap ike motd pflog syscons
adjkerntz inetd mountcritlocal power_profile sysctl
amd initdiskless mountcritremote ppp-user syslogd
apm initrandom mountd pppoed timed
apmd ip6addrctl moused preseedrandom tmp
archdep ip6fw mroute6d pwcheck ugidfw
atm1 ipfilter mrouted quota usbd
atm2 ipfs msgs random var
atm3 ipfw named rarpd vinum
bgfsck ipmon natd rcconf.sh virecover
bootparams ipnat netif resolv watchdogd
ccd ipsec netoptions root ypbind
cleanvar ipxrouted network_ipv6 route6d yppasswdd
cleartmp isdnd nfsclient routed ypserv
cron jail nfsd routing ypset
devd kadmind nfslocking rpcbind ypupdated
devfs kerberos nfsserver rtadvd ypxfrd
dhclient keyserv nisdomain rwho
dmesg kldxref nsswitch savecore
It seems to determine what to run, and which priority at
startup/shutdown by a code block at the top :
# PROVIDE: named
# REQUIRE: SERVERS cleanvar
# BEFORE: DAEMON
# KEYWORD: shutdown
# PROVIDE: syslogd
# REQUIRE: mountcritremote cleanvar
# BEFORE: SERVERS
And then calls "rcorder" to determine the order. When you
do a shutdown, it just does the order backwards (And some other
stuff, but in general). It passes "stop" to them, and some of the
scripts have "start/stop" case statements like for a supplemental
program "avahi" (The ones in rc.d were too long to show complete):
checkyesno avahi_daemon_enable && echo "Starting avahi-daemon." && \
checkyesno avahi_daemon_enable && echo "Stopping avahi-daemon." && \
We also don't have an inittab. Our init can only be
called with what "security level" you want it to, not run level.
So, it seems, it doesn't operate in that manner at all.

Ok. I just need to figure out what happens AFTER that
rc.shutdown is called. I guess I'll be starting/stopping my machine
alot later today to see what happens after rc.shutdown is called
and figure out where it is.
