why I use storage with lvm encryption in preseed/user-data ,but encryption is not working? about cubic HOT 1 OPEN

Hi @PJ-Singh-001
I use the following way to make the ecryption work:

1. use there #101 (comment)
   manually set storage with interactive-sections: so I can input passphrase...

2. after half-auto installed successfully, cd /var/log/installer to get auto-installer-user-data as : (I find this important step online) so that I get the storage user-data setting in the whole files
   #cloud-config
   ....
   storage:
   config:

3. I use the part of storage user-data, and add it at #101 (comment)

the autoinstallation works in virtualbox virtual machines installation.
I need to change the storage size not use the fix size or something else for hardware installation. I think It will work.
