systemd-cryptsetup/systemd-cryptenroll:
+ * The device node argument to systemd-cryptenroll is now optional. If
+ omitted it will be derived automatically from the backing block
+ device of /var/ (which quite likely is the same as the root file
+ system, hence effectively means if you don't specify things otherwise
+ the tool will now default to enrolling a key into the root file
+ system's LUKS device).
+
* systemd-cryptenroll can now enroll directly with a PKCS11 public key
(instead of a certificate).
