+
+Some commands in order to clean and prepare a container to become a template.
+
+1. The script will :
+  * Allow root's connection to SSH with password.
+  * Reconfigure timezone to **Europe/Paris**.
+  * Reconfigure locales to **en_US.UTF-8**.
+  * Download an additionnal script use by our preseed with PXE to configure logs (rsyslog, logrotate,…).
+  * Remove **x11** useless packages.
+  * Clean some stuff (downloaded packages, empty logs,…).
+2. How-to use :
+
+``` sh
+wget https://git.ipr.univ-rennes1.fr/cellinfo/scripts/raw/master/proxmox/proxmox.template.debian.sh -O /tmp/proxmox.template.debian.sh
+chmod +x /tmp/proxmox.template.debian.sh
+/tmp/proxmox.template.debian.sh
+```
+
+#### vzdump-hook-lxc-stretch-template.pl
 
 This script must be used as a vzdump's hook (the backup utility for CT and VMs for Proxmox).
 
 1. The script will :
-  * Remove the templates oldest than 2 days (by default).
   * Copy the current dump as a template in **/mnt/zfsbkp/template/cache** (by default).
+  * Unlink **$TEMPLATE_FILE_LINK**.
+  * Link **$TEMPLATE_FILE_LINK** to the last dump in order to have a better name.
+  * Remove the templates oldest than 2 days (by default).
 2. How-to use :
   * Define a backup as usual (in the Proxmox's webgui) and prefer to select only one container.
-  * In command on the hypervisor, open **/etc/pve/vzdump.cron** and edit the line of the new dump to add : **--script /usr/local/bin/vzdump-hook-lxc-template.pl**.
+  * In command on the hypervisor, open **/etc/pve/vzdump.cron** and edit the line of the new dump to add : **--script /usr/local/bin/vzdump-hook-lxc-stretch-template.pl**.
 3. Customization :
   * If you don't store template in the default path (**/mnt/zfsbkp/template/cache**), please edit the variable **$TEMPLATE_DIR** in the script.
+  * You might want to set another template name, please edit the variable **$TEMPLATE_FILE_LINK** in the script.
+
+#### vzdump-hook-lxc-jessie-template.pl
+
+Same as above but set jessie in **$TEMPLATE_FILE_LINK**.
