Description of problem:

As commented by egdoc the change https://github.com/rhinstaller/anaconda/commit/a8b4f2d547f5ea987e52b32e33bc323c7aa21442 "makes impossible to perform a kickstart installation on an already existing LUKS container. This is usually done by opening the LUKS container in the %pre section of the kickstart file, and then re-using the decrypted partition or lvm logical volumes. Since the container is not opened by anaconda, the device doesn't get a key, therefore the installation is aborted."

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.
2.
3.

Actual results:
"The existing unlocked LUKS device X cannot be used for the installation without an encryption key specified for this device. Please, rescan the storage."

Expected results:
To be able to reuse partition in kicstart :
logvol / --name=root --vgname=fedora_x --useexisting
logvol swap --name=swap --vgname=fedora_x --noformat
logvol /home --name=home --vgname=fedora_x --noformat
part /boot --onpart=sda2
part /boot/efi --onpart=sda1 --noformat

after an 'cryptsetup luksOpen ...' in %pre section

Additional info
We have to create an updates.img to remove 'self.add_check(verify_unlocked_devices_have_key)' and bypass the pb
