  Confirmed

Bug description:
  Dracut does not support booting from an encrypted ZFS volume. Steps to
  reproduce:

  1. In a VM install Ubuntu 24.10 with an encrypted ZFS volume
  2. Install dracut afterwards: sudo apt install dracut zfs-dracut
  3. Add rd.shell to the boot arguments
  4. Reboot

  The boot will fail:

  ```
  dracut-pre-mount[817]: Warning: ZFS: Key /run/keystore/rpool/system.key for rpool hasn't appeared. Trying anyway.
  dracut-pre-mount[863]: Key load error: Failed to open key material file: No such file or directory
  [FAILED] Failed to mount sysroot.mount - /sysroot.
  ```

  The initrd should have asked for the password, but it did not.
