As the default is to use a random id, this would cause 50% of isos to be bad. there are two possible ways to solve this: a) the most significant bit is cleared early enough (e.g. &=0x7fffffff right after parsing the -i param and after generating a random id value) b) the whole code is made to work cleanly with 32-bit/unsigned id values -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
