+          message is now written to the logs (but the value is nonetheless
+          accepted). Setting User=nobody is unsafe, since the primary purpose

+          locally. It's in particular used by the NFS subsystem and in user
+          namespacing. By running a service under this user's UID it might get
+          read and even write access to all these otherwise unmappable files,
+          which is quite likely a major security problem.

         * A new kernel command line option systemd.hostname= has been added
           that allows controlling the hostname that is initialized early during
           boot.

+        * systemd-homed now supports unlocking home directories with FIDO2
+          security tokens that support the 'hmac-secret' extension, in addition
+          to the existing support for PKCS#11 security token unlocking

+        * homectl's --pkcs11-uri= setting now accepts two special parameters:
+          if "auto" is specified and only one suitable PKCS#11 security token
+          is plugged in, its URL is automatically determined and enrolled for

         * The /etc/crypttab tmp option now optionally takes an argument

           changed from ext2 to ext4.
