Subject: Prochain creneau pour mise a jour de votre serveur $hostname
|
|
X-Debian-Release: $local_release
|
|
X-Packages: $packagesParsable
|
|
X-Date: $date
|

|
|
Bonjour,
|
|
|
|
Des mises-à-jour de sécurité ou mineures sont à réaliser sur votre serveur
|
|
${hostname}.
|
|
Sauf indication contraire de votre part, le prochain créneau prévu pour
|
|
intervenir manuellement pour réaliser ces mises-à-jour est :
|
|
${date}
|
|
|
|
Si nous intervenons, un redémarrage des éventuels services concernés sera
|
|
réalisé, entraînant a priori quelques secondes de coupure. Si nous ne sommes
|
|
pas intervenus sur ce créneau, vous recevrez une nouvelle notification la
|
|
semaine prochaine.
|
|
|
|
Voici la listes de packages qui seront mis à jour :
|
|
|
|
$(cat $packages)
|
|
|
|
Liste des packages dont la mise-à-jour a été manuellement suspendue :
|
|
|
|
$(cat $packagesHold)
|
|
|
|
Liste des services qui seront redémarrés :
|
|
|
|
$(cat $servicesToRestart)
|
|
|
|
N'hésitez pas à nous faire toute remarque sur ce créneau d'intervention le plus
|
|
tôt possible.
|
|
|
|
Cordialement,
|
|
