I think we could split that in two different issues, I've cloned this
bug, see: #805155
The attached patch is calling the new "panic" scripts just before
dropping to a shell, this can be then used by plymouth package to ensure
the plymouth daemon is killed/the splash hidden

be use for example to disable a splash screen.
