cron-atp contrôle de manière automatique que le système est à jour. Si un paquet est à mettre à jour, cron-apt envoie une alerte par mail.

apt-get install cron-apt

# Configuration for cron-apt.

# The email address to send mail to.
MAILTO="root"

# When to send email about the cron-apt results.
# Value: error   (send mail on error runs)
#        upgrade (when packages are upgraded)
#        changes (mail when change in output from an action)
#        output  (send mail when output is generated)
#        always  (always send mail)
#                (else never send mail)
MAILON="upgrade"

# If this is non-empty, it will be used as the host name in subjects of
# generated e-mail messages. If this is empty, the output of uname -n
# will be used.
HOSTNAME="MyHost"

cron-apt enverra un mail à root - voir le paramétrage d'exim pour le destinataire associé à root - lorsqu'une mise à jour - upgrade - sera disponible.
