Shell pseudocode was posted to this thread (a month ago?) that showed how the init scripts could handle the requirement that /run be mounted early, even if it's not on the root fs. The init scripts already include special handling of /proc and /, IIRC; one more special-cased directory isn't technically infeasible, and unless someone decides to move /run elsewhere, it should be the last mount point that ever needs to be special cased wrt mtab. -- Steve Langasek postmodern programmer
