full disk encryption with luks on manjaro xfce

* a manjaro x86_64 VM with X (see https://gitlab.manjaro.org/manjaro-arm/a.../issues/10 for the reason behind the X requirement) with an extra disk (in my case, I've used a 8gb qcow2 empty file mapped as sata, so it is /dev/sda in the VM)
* ssh into it
* clone the https://gitlab.manjaro.org/manjaro-arm/a...-installer repo
* install the required packages (dialog and manjaro-arm-qemu-static in my case)
* apply the patch (git apply)
* run export CRYPT=y, then the installer. It will ask you user/pass/software selection/keyboard/etc. then the luks password twice (first one to create the device, the second one to mount it)

Then, power off the manjaro VM, plug a microsd into your computer and convert the qcow2 image into a raw one, then flash it to your microsd (or do it at once as qemu-img convert -f qcow2 -O raw manjaro-usb.qcow2 /dev/mmcblkX)

Plug it into your pbp and profit!

In order to resize the luks partition:

* `parted /dev/mmcblkX`, then `resizepart NUMBER END` (in my case, partition = 2, end = 125GB)
* `cryptsetup resize /dev/mapper/ROOT_MNJRO`
* `resize2fs /dev/mapper/ROOT_MNJRO`

HTH!

Edit: I've tested with the console parameter as suggested and it doesn't work, so I'll keep it that way.

Amazing, Thank you!

sidenote - If you put a bad password in, the script will happily continue. (yes, I know, I was going to change it later)

Enter passphrase for /dev/sda2:
Password quality check failed:
 The password fails the dictionary check - it is based on a dictionary word
Device /dev/sda2 is not a valid LUKS device.
Device /dev/sda2 is not a valid LUKS device.
mount: /var/tmp/manjaro-arm-installer/root: special device /dev/mapper/ROOT_MNJRO does not exist.
