Did you by any chance happend to run the weekly/320.makewhatis periodic
script that night? It is enabled by default. However, you shouldn't
need it if you maintain your system entirely through freebsd-update.

freebsd-update is a shell script, so it's fairly easy to see the
difference between 'fetch' and 'cron' -- look for the functions
'cmd_fetch()' and 'cmd_cron()' in the code (they're right next to each
other.)
The differences are:
'fetch' tests that is is connected to a tty and complains about not
being run interactively if not
'cron' sleeps for a random number of seconds up to 1 hour, and it
logs everything it does to a temporary file in order to mail
back a report to the user if needed.
Otherwise, they both call exactly the same 'fetch_check_params()' and
'fetch_run()' functions.
Cheers,
Matthew
# Fetch command. Make sure that we're being called
# interactively, then run fetch_check_params and fetch_run
cmd_fetch () {
if [ ! -t 0 -a $NOTTYOK -eq 0 ]; then
echo -n "`basename $0` fetch should not "
echo "be run non-interactively."
echo "Run `basename $0` cron instead."
exit 1
fi
fetch_check_params
fetch_run || exit 1
}
# Cron command. Make sure the parameters are sensible; wait
# rand(3600) seconds; then fetch updates. While fetching updates,
# send output to a temporary file; only print that file if the
# fetching failed.
cmd_cron () {
fetch_check_params
sleep `jot -r 1 0 3600`
TMPFILE=`mktemp /tmp/freebsd-update.XXXXXX` || exit 1
if ! fetch_run >> ${TMPFILE} ||
! grep -q "No updates needed" ${TMPFILE} ||
[ ${VERBOSELEVEL} = "debug" ]; then
mail -s "`hostname` security updates" ${MAILTO} < ${TMPFILE}
fi
rm ${TMPFILE}
}
