+       hostname=       [KNL] Set the hostname (aka UTS nodename).
+                       Format: <string>
+                       This allows setting the system's hostname during early
+                       startup. This sets the name returned by gethostname.
+                       Using this parameter to set the hostname makes it
+                       possible to ensure the hostname is correctly set before
+                       any userspace processes run, avoiding the possibility
+                       that a process may call gethostname before the hostname
+                       has been explicitly set, resulting in the calling
+                       process getting an incorrect result. The string must
+                       not exceed the maximum allowed hostname length (usually
+                       64 characters) and will be truncated otherwise.
