It's bedouin, IIRC.
The R reset command won't actually work for you, if that's what you were considering.
As for truely randomized exits, that might need to be coded, but one thing you COULD do is to set up some sort of rand_prog in the enterance room to the camp that fires itself every so often. It would delete whatever previous exit from the camp there is, and choose from a series of new ones using the rand ifcheck. It would then need to go make another exit leading into the camp in whatever room it chose with another mpopenpassage.
If that made no sense, which I'm sure it probably didn't, I'll see if I can scribble down some code for it.
