Subject: [PATCH] Abort if switch_root does not exist. Otherwise it would
 succeed silently when we KNOW it would fail, which is not cool. Usually this
 means you didn't build switch_root in your dracut checkout and you used
 dracut -l. (This currently cannot be done in a check script, because of the
 current design of check. Andreas intends on discussing a redesign on the
 list.)
