BUT the machine in question is a 3B15 in which run level 6 is equivelent to INIT 0 (halt) and then boots to the specified initdefault, this is off limits on a 3B15! This is not ment to be a flame just informational. And just for the record init level 5 is also off limits on a 15 (this is firmware mode) Ken A.
