Thanks! Looks like Edubuntu 12.04 contains your 50-cron, but 50-set-time
is different, and the Edubuntu version doesn't run hwclock:
richard@bserve:/opt/ltsp/i386/usr/share/ltsp/init-ltsp.d# cat 50-set-time
# This file is sourced
if [ -n "$TIMEZONE" ] && [ -e "/usr/share/zoneinfo/$TIMEZONE" ]; then
cp /usr/share/zoneinfo/$TIMEZONE /etc/localtime 2>/dev/null
fi
if [ -n "$TIMESERVER" ]; then
# Set timeserver to $SERVER if set to autodetect
if [ "$TIMESERVER" = "auto" ]; then
TIMESERVER=${SERVER}
fi
# Modify /etc/ntp.conf
sed -i -e '/^server/d' /etc/ntp.conf
echo "server ${TIMESERVER}" >>/etc/ntp.conf
# Modify /etc/default/ntpdate
sed -e 's/^NTPSERVERS=".*"/NTPSERVER="'$TIMESERVER'"/'
/etc/default/ntpdate
fi
richard@bserve:/opt/ltsp/i386/usr/share/ltsp/init-ltsp.d# cat 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
