Where can a curious bystander get that look ? I only found a diff from february 8: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/pcmemtest.html where i see in the isoinfo output only differences of user id, group id, and timestamps of /boot and /boot/floppy.img. The patch in the original message of this bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=1005197;filename=pcmemtest.diff.txt;msg=5 should fix both. > Perhaps looking through > the xorriso manual page would be helpful, as there are a number of header > checksums in such files. If SOURCE_DATE_EPOCH is set then all automaticly generated ids in the ISO meta data should be reproducibly derived from that time value. If all input is the same, then all checksums should be the same. If not, it would be a bug in xorriso. (I just tested a mock-up of the xorrisofs run in pcmemtest.diff.txt. Both resulting ISOs were identical.) ---------------------------------------------------------------------- Side note: The gesture find iso -print0 | xargs -0r touch --date="@$(SOURCE_DATE_EPOCH)" could be replaced by xorrisofs option --set_all_file_dates "=$SOURCE_DATE_EPOCH" which acts on the files in the emerging ISO filesystem rather than on the input files on hard disk. (The '=' is xorriso's equivalent of date's '@'. See man xorriso, command -alter_date .) Have a nice day :) Thomas
