I always wondered why debian-cd and debian-live rely on file paths with such low entropy. No individual distinction between versions is recognizable. So two live ISOs in two DVD drives or USB sticks could cause quite some confusion. > 4) And, well, I might try an obvious patch that searches with regex both > /live/vmlinuz and /live/vmlinuz1 and give us more feedback about it. Or a dedicated unique identification file path ? An empty file in an alreay existing directory would cost 0 or 2048 bytes in the ISO. Even in a conservative 8.3 name it would be possible to expose 56 bit with a birthday paradox threshold of 256 million. A plain hex encoding could expose 44 bit of random id (~ 4 million children in the class). If reproducibility is of concern, then the filename could be derived from some version-dependent strings like the ISO's volume id. All mangled through md5sum and tr 'a-f' 'A-F', the first eleven result characters would yield a quasi-unique DOS style file name. Have a nice day :) Thomas
