always, use caution when formatting any disk. You could lose valuable information if you format
the wrong disk or partition.

The USB key is now ready and can be booted with the “Live USB Persistence” boot menu entry.
9.4.3. Setting Up Encrypted Persistence on a USB Key
live-boot
is also able to handle persistence file systems on encrypted partitions. You can thus
protect the data of your persistent directories by creating a LUKS encrypted partition holding the
persistence data.
The initial steps are the same up to the creation of the partition but instead of formatting it with
an ext4 file system, use
cryptsetup
to initialize it as a LUKS container. Then open that container
and setup the ext4 file system in the same way as in the non-encrypted setup, but instead of using
the
/dev/sdb3
