I'd suggest looking at the Btimes of top level directories

For me, that gets the Nov 21 2009 date, which is earlier than my
install date.
So far, /etc/hostid and the /home symlink seem to be the winners.
On my system /etc/hostid is several days later than my actual install
date, so that isn't always reliable. You might want to create a file
with the timestamp you want. The most likely time appears to me to be
the 'Created' time in /etc/rc.conf, as someone suggested earlier. The
following code will extract that and create a file with that timestamp.
I have checked it on my system, but use at your own risk.
file=/etc/install_date
date=$(grep '^# Created: ' /etc/rc.conf | cut -c 12-80)
tdate=$(date -j -f "%a %b %d %H:%M:%S %Y" "$date" "+%Y%m%d%H%M.%S")
echo $date> $file
touch -t $tdate $file
chmod -w $file
chflags schange $file
I finally agreed for /home symlink. I've made a mistake. To be sure the
link and not the directory /usr/home is touched the best to do is :
# chflags -h uchg /home
-h means "not following links"
