+Example of simple dracut module for reencryption of system
+LUKS drive on-the-fly.
+
+Install in /usr/[share|lib]/dracut/modules.d/90reencrypt, then
+build special initramfs "with dracut -a reencrypt -o crypt".
+Reencrypt module doesn't work (has a conflict) with crypt module as
+of now. After successful reencryption reboot using original initramfs.
+
+Dracut then recognize argument rd.luks.reencrypt=name:size,
+e.g. rd.luks.reencrypt=sda2:52G means only 52G of device
+will be reencrypted (default is whole device).
+(Name is kernel name of device.)
+
+If there's more than single active keyslot in the target luks device
+you're required to select one keyslot explicitly for reencryption via
+rd.luks.reencrypt_keyslot=<keyslot_number> option. Bear in mind that
+if you use this option, all other keyslots will get deactivated in the
+process.
+
+Another argument, rd.luks.reencrypt_key=/dev/sda:/path/to/keyfile
+can be used to read password for specific keyslot from device containing
+filesystem with a keyfile (file with a password). If you omit reencrypt_key
+argument, reencryption would work only in case a LUKS container has
+exactly one keyslot activated.
+
+Arguments rd.luks.reencrypt_keyslot and rd.luks.reencrypt_key are not
+mandatory.
+
+Note that reencryption context is stored in ramdisk, any
+fail can mean complete lost of data!
