Configuration

Edit /etc/default/dextrose-update configuration file to set space separated list of yum repositories: 

DEXTROSE_YUM_REPO="dextrose dextrose-freeworld"

Install

Create /usr/sbin/dextrose-update, main execution file: 

#!/bin/sh

name="dextrose-update"
. /etc/default/${name}

logfile="/var/log/${name}"

reboot_pkgs="kernel kernel-firmware"
relogin_pkgs="sugar sugar-artwork sugar-base sugar-datastore sugar-presence-service sugar-toolkit"

yum="/usr/bin/yum --disablerepo=* --skip-broken --quiet"
for i in $DEXTROSE_YUM_REPOS; do
   yum="$yum --enablerepo=$i"
done

updates() {
    ${yum} -e0 check-update | awk '/./{print $1 "-" $2}'
}

to_update=$(updates)
[ "${to_update}" ] || exit 0

parse() {
    for i in $@; do
        echo ${to_update} | grep "\(^\| \)$i\." >/dev/null && echo $i
    done
}

need_reboot=$(parse ${reboot_pkgs})
need_relogin=$(parse ${relogin_pkgs})

echo "$(date)" >> $logfile
echo -e "\tRepository:" ${DEXTROSE_YUM_REPO} >> $logfile
echo -e "\tPackages to update:" ${to_update} >> $logfile
${yum} -y update >> $logfile 2>&1
to_update=$(updates)

if [ "${need_reboot}" ]; then
    if [ "${need_reboot}" != "$(parse ${reboot_pkgs})" ]; then
        echo -e "\tNeed to reboot..." >> $logfile
        dbus-send --system /org/sugarlabs/system org.sugarlabs.system.Reboot
    fi
fi

if [ "${need_relogin}" ]; then
    if [ "${need_relogin}" != "$(parse ${relogin_pkgs})" ]; then
        echo -e "\tNeed to relogin..." >> $logfile
        dbus-send --system /org/sugarlabs/system org.sugarlabs.system.Relogin
    fi
fi

Create cron task: 

ln -s /usr/sbin/dextrose-update /etc/cron.daily/

Python client code for src/jarabe/model/notifications.py: 

_DBUS_SYSTEM_IFACE = 'org.sugarlabs.system'

_SYSTEM_RELOGIN_ID = -2
_SYSTEM_TIMEOUT = 5

systembus = dbus.SystemBus()
systembus.add_signal_receiver(self.__reboot_cb, 'Reboot', _DBUS_SYSTEM_IFACE)
systembus.add_signal_receiver(self.__relogin_cb, 'Relogin', _DBUS_SYSTEM_IFACE)

def _system_alert(self, replaces_id, app_icon, message):
    self.notification_received.send(self,app_name='system',
            replaces_id=replaces_id, app_icon=app_icon,
            summary=_('System alert'), body=message,
            actions=[], hints={}, expire_timeout=_SYSTEM_TIMEOUT)

def __reboot_cb(self):
    self._system_alert(_SYSTEM_REBOOT_ID, 'system-restart',
            _('Please, reboot your computer to take into account ' \
                    'new updates'))

def __relogin_cb(self):
    self._system_alert(_SYSTEM_RELOGIN_ID, 'system-logout',
            _('Please, restart Sugar to take into account ' \
                    'new updates'))
