-Now it is time to customize your environment; you can for example:
+Now it is time to customize your environment; check the **[[https://grml.org/config/grml-autoconfig.1.html|grml-autoconfig]]** man page about the options to automatically install **Debs**, **Configuration** and **Scripts** into a freshly booted GRML environment.
+You can for example:
   * Generate an SSH RSA key running the **ssh-keygen** utility. The key will be saved into ''$HOME/.ssh/''.
   * Customize the shell by editing the **$HOME/.zsrc** file, e.g. by adding alias commands, customizing the **PATH** or other environment variables. etc.
   * Run and configure some programs that will save preferences into the **$HOME/**, e.g. the Midnight Commander **mc** will save its files into ''$HOME/.config/mc/''.
+  * Create an ''$HOME/config/'' directory and place what you want in it. You will find that directory again at the next boot.
+At the end of the customization, run the GRML command:
+<code>
+save-config -all
+</code>
+A file named **config.tbz** will be saved into the current directory. The file is a //grml configuration archive//, which may contains several components: hidden files from the ''$HOME'' directory, modified files from the ''/etc/'' directory, etc.
+Mount the custom partition and copy the file into its root directory:
+<code>
+mkdir /mnt/grmlcfg
+mount /dev/sdc3 /mnt/grmlcfg
+cp -p config.tbz /mnt/grmlcfg
+</code>
+If you want to modify the **config.tbz** archive without re-creating it via the ''save-config'' command, you can extract the archive and then re-create it:
+<code bash>
+mkdir config
+cd config
+tar jxvf ../config.tbz
+# Do whatever you need to the extracted files...
+mv ../config.tbz ../config.bak.tbz
+tar jcvf ../config.tbz *
+</code>
+==== Add scripts and other files to the USB ====
+If you want to have some scripts run at bootstrap by GRML, create a **script/** directory into the root of the custom USB partition, and place the scripts into it. During the execution of the script the partition will be mounted under **/mnt/grmlcfg/**.
+You can place also files into the partition, so e.g. you can install additional deb packages on-the-fly.

 ===== Boot via PXE =====

 Vedere [[install]].
 ===== Personalizzazione =====
 La partizione VFAT quando il sistema live è avviato, risulta accessibile sotto **''/lib/live/mount/medium/''**.
-FIXME (Verificare se funziona davvero) Se nella chiavetta USB contenente GRML si crea un archivio **''config.tbz''**, questo verrà scompattato subito dopo l'avvio a partire dalla directory radice. L'archivio deve essere un **//grml configuration archive//**, abbreviato GCA.
-FIXME (Verificare se funziona davvero) dopo l'autoconfigurazione viene eventualmente eseguito lo script **''DCSDIR/scrips/grml.sh''**. Vedere il paragrafo [[http://grml.org/config/grml-autoconfig.1.html|Determination of DCS directory]], dovrebbe trattarsi comunque della directory radice della partizione VFAT.
 La via più comoda di avere una GRML personalizzata è passare il parametro **''netconfig=server/archivio.tar.bz2''** al boot prompt. L'archivio viene scompattato subito dopo l'avvio a partire dalla directory radice, ovviamente è necessario che la macchina abbia accesso alla rete.
