+Unless this has already been done, you must partition, optionally
+encrypt, and then format the target partitions.
Preferably, assign partitions a label so that you can easily and
reliably refer to them in @code{file-system} declarations (@pxref{File
Systems}). This is typically done using the @code{-L} option of
@command{mkfs.ext4} and related commands.
+A typical command sequence may be:
+
+@example
+# fdisk /dev/sdX
+@dots{} Create partitions etc.@dots{}
+# cryptsetup luksFormat /dev/sdX1
+# cryptsetup open --type luks /dev/sdX1 my-partition
+# mkfs.ext4 -L my-root /dev/mapper/my-partition
+@end example
