ntpd, on Current at least, has its startup script pull in
/etc/default/ntp, in which you can set the "-g" option. It might be the
default for all I know. This is mine:

NTPD_OPTS="-g -p /run/ntpd.pid -u ntp:ntp"

Since I'm answering this thread anyway, here's my rc.local:
#!/bin/bash
#
# /etc/rc.d/rc.local:  Local system initialization script.
#
# Put any local startup commands in here.  Also, if you have
# anything that needs to be run at shutdown time you can
# make an /etc/rc.d/rc.local_shutdown script and put those
# commands in there.

# Make sure these filesystems have the proper attributes as
# per /etc/fstab. Mounting efivarfs with rw enabled is dangerous.
mount -o remount efivarfs
mount -o remount proc

if [ -x /etc/rc.d/rc.redis ]; then
  # Start Redis daemon
  echo "Starting Redis daemon:    /etc/rc.d/rc.redis start"
  /etc/rc.d/rc.redis start
fi

# Pulse Audio has a HOME set in /etc/passwd, but no actual 
# directory corresponding to it. Create it now.
mkdir -p /var/run/pulse
chgrp pulse /var/run/pulse

# Start system monitoring daemon as root. It will drop privs.
# If it is started by a user and gets whacked, they will get
# user privs of that user. Better to be run as 'nobody'.
# See /etc/gkrellmd.conf for options
gkrellmd

## EOF

Explaination: for some reason, efivars remains r/w by default. If it
stays that way, an errant command that writes into the /sys area where
the efivars are could scribble over them, bricking the firmware.

efivarfs	/sys/firmware/efi/efivars efivarfs	noauto,ro	

For /proc, I use 'hidepid' so users can't spy each other's command
lines. For some reason, this doesn't keep set even though it's in fstab:
proc            /proc            	proc        	hidepid=2

Checking the passwd file (pwck) will generate an error for user 'pulse'
due to no home being there on startup because it gets deleted on reboot,
so that fixes that issue. Redis and gkrellmd are self-explainitory.

After that, in /etc/default/tmp-cleanup, I have:
# You may also run a custom cleanup script by pointing to it here:
TMP_REMOVE_SCRIPT=/usr/local/sbin/mightytidy.py

Which was posted to LQ in a thread about said topic and is duplicated
here:

#!/usr/bin/python3
## Remove various temporary files from the system. Ideally, these
## files are left over from applications that do not remove their
## own temp files on closure. This script should be run at boot
## time, hooked into the system startup scripts.

You can increase 'hitList' as needed. Personally, I like to keep /tmp
until I decide to remove things from it because I park files there
alot. The script only deletes junk that gets left behind and nothing
else. 

After *that*, I start Privoxy + Tor + I2p routers for darknet
access. Other networking protocols I start by hand, just in case
something breaks.
