I would test Btrfs with encryption (LUKS) before I do this on my new Host.
I have doing this with calamares Installer created sda1 at / with Btrfs and password for LUKS set boot flag. And installed the system all fine.
Rebooted the VM typed in the LUKS password. And then Lightdm comes up but do no auto login. I typed in the User password nothing happened.
The LUKS and user password was the same
What I’m doing wrong here?
