Comment 37 for bug 538214

Based on discussion on IRC today, I understand it's possible to get us booting to the DM consistently, possibly at the expense of also leaving server installs at the splash screen instead of the login prompt. I think this is the right tradeoff for us to make for beta1 (reopening bug #506297), so resetting the milestone; if we end up deferring to beta-2, this should certainly be documented in the errata.
