In short, this was intentional -- the goal is that this feature will be turned on permanently, at which point there's no sense in having yet another useless mount option laying around. IIRC, the license is written such that you are not *allowed* to make this a mount option, for this reason. Kirk is really serious about this. You should read the Ganger & Platt paper, as well as the other documentation written by Kirk on this subject. -- Brad Knowles, "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
