I don't see how that's particularly relevant. In all cases, the root filesystem must be resolved and mounted before any init program can be run, and this was true even with init=/linuxrc. At any rate, if there are no other arguments one way or the other, I think consistency is most important here and that alpha should follow i386's lead on this point. -- Steve Langasek postmodern programmer
