+===== Hostname =====
+The host name is persisted in ''/etc/hostname'' and can be shown with ''hostname'' or (using the systemd-way) with ''hostnamectl''.
+To change the host name
+  - use ''sudo hostname <NAME>'' to set the host name now (would not survive a reboot)
+  - edit ''/etc/hostname'' to set it permanently
+  - edit ''/etc/hosts'' to properly map the new host name to localhost
+Instead of the first two steps you can also use
+<code bash>
+hostnamectl set-hostname <NAME>
