+Subject: Prochain creneau pour redemarrage de votre serveur $hostname
+X-Date: $date
+
+Bonjour,
+
+Le noyau de votre serveur doit être mis à jour. Pour cela nous devons
+redémarrer votre machine ${hostname}.
+
+Sauf indication contraire de votre part, le prochain créneau prévu pour
+mettre à jour le noyau de votre serveur est :
+Le ${date}, ${hour}.
+
+Si nous intervenons, un redémarrage complet du serveur sera réalisé, entraînant
+plusieurs minutes de coupures. Nous nous assurerons de vérifier le bon
+démarrage de la machine ainsi que de ses services.  Si nous ne sommes pas
+intervenus sur ce créneau, vous recevrez une nouvelle notification le mois
+prochain.
+
+Votre version actuelle du noyau : $currentKernel
+Après redémarrage votre version sera : $nextKernel
+
+N'hésitez pas à nous faire toute remarque sur ce créneau d'intervention le plus
+tôt possible.
+
+Cordialement,
+-- 
+Équipe Evolix <equipe@evolix.fr>
