Most functionality has been moved to init-ltsp.d scripts...
In upstream LTSP, which may be slightly different from what made it into Ubuntu
12.04...
TIMEZONE, TIMESERVER and HWCLOCK are implemented in
/opt/ltsp/i386/usr/share/ltsp/init-ltsp.d/50-set-time:
# Set up timezone
if [ -n "$TIMEZONE" ] && [ -e "/usr/share/zoneinfo/$TIMEZONE" ]; then
cp /usr/share/zoneinfo/$TIMEZONE /etc/localtime 2>/dev/null
fi
# Set timeserver to $SERVER if set to autodetect
if [ "$TIMESERVER" = "auto" ]; then
TIMESERVER=${SERVER}
fi
# Set up timeserver
if [ -n "$TIMESERVER" ]; then
ntpdate -p 1 $TIMESERVER && hwclock --systohc --${HWCLOCK:-"utc"}
--noadjfile || true
fi
if no HWCLOCK is set, it defaults to utc.
SHUTDOWN_TIME is implemented in
/opt/ltsp/i386/usr/share/ltsp/init-ltsp.d/50-cron:
CRON_FILE=/etc/cron.d/ltsp
if [ ! -w "/etc/cron.d" ]; then
echo "Warning: /etc/cron.d is not writeable."
return 1
fi
if [ -n "$SHUTDOWN_TIME" ] ; then
echo $SHUTDOWN_TIME | awk -F : '{print $2" "$1" * * * root test ! -S \"$(ls
-1 /var/run/ldm_socket_* | head -1)\" && PATH=\$PATH:/sbin/ poweroff" }' >>
$CRON_FILE
fi
env | sed -n 's/^CRONTAB_[0-9][0-9]=//p' >> $CRON_FILE
