yacy_search_server/htroot/ConfigBasic.java
orbiter 01e0669264 re-designed some parts of DHT position calculation (effect is the same as before)
and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary
