The mini-kernel needs to minimal boot (thus the init 1) to collect info as we don't really know why the original kernel crashed.
This is use error -- use "1" not "init 1", (and it probably needs to be at the very end of the command line.) But we've discussed what we're doing here and I think you'll be loading a different initrd for that kernel, so I don't think that's going to matter anyway.
