Public bug reported:
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.
