Step 6
Set Up Persistence on Kali LiveChoosing one of the persistence options doesn't mean it'll work out of the box. There is some configuration to perform first, mainly creating a new partition to save all your data. Kali has some excellent instructions on doing so, which we are using.
To create a partition above the Kali Live partitions, ending at 7 GB, issue the following three commands in a terminal window as the kali user, which will keep the Live options in the 7 GB partition, freeing up the rest for your data storage. Make sure you're doing this from your Kali Live system you just booted into.
~$ end=7GiB ~$ read start _ < <(du -bcm kali-linux-2021.1-live-arm64.iso | tail -1); echo $start ~$ parted /dev/sdb mkpart primary ${start}MiB $end
When that's done, you should now have a third partition labeled something like /dev/sdb3 or /dev/disk1s3. Check your volume identifier because you'll need it for the rest of this process.
If you want to add some encryption in case you think someone might get a hold of your drive, issue the following two commands as kali. Type "YES" in all caps if prompted to proceed with overwriting the new partition. When asked for a passphrase, choose one and enter it twice. You can skip encryption if you don't want it.
~$ cryptsetup --verbose --verify-passphrase luksFormat /dev/sdb3 ~$ cryptsetup luksOpen /dev/sdb3 my_usb
Next, run the following two commands as kali to create an ext3 file system labeled "persistence." If you chose to skip encryption, use these:
~$ mkfs.ext3 -L persistence /dev/sdb3 ~$ e2label /dev/sdb3 persistence
If you encrypted the partition, use:
~$ mkfs.ext3 -L persistence /dev/mapper/my_usb ~$ e2label /dev/mapper/my_usb persistence
Next, create a mount point, mount the new partition there, create a configuration file to enable persistence, then unmount the partition. If you didn't encrypt the partition, use:
~$ mkdir -p /mnt/my_usb ~$ mount /dev/sdb3 /mnt/my_usb ~$ echo "/ union" > /mnt/my_usb/persistence.conf ~$ umount /dev/sdb3
If you encrypted the partition, use:
~$ mkdir -p /mnt/my_usb/ ~$ mount /dev/mapper/my_usb /mnt/my_usb ~$ echo "/ union" > /mnt/my_usb/persistence.conf ~$ umount /dev/mapper/my_usb
If you didn't encrypt the partition, you're done. If you did, you have one more command to issue as kali, which will close the encrypted channel for the new partition:
~$ cryptsetup luksClose /dev/mapper/my_usb
Now, reboot into Kali Live and choose the appropriate system, and everything should be all set.
