zfs-load-key.sh is called by the dracut-pre-mount.service unit which has no explicit 'After' dependency on zfs-import.target. That way it can be that the pool has not yet been imported and the zfs-load-key.sh finishes without ever seeing the relevant pool. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Lorenz Hüdepohl <dev@stellardeath.org> Closes #11500
