Bug#505381: genisoimage: writes blank sectors
OK, some updates for 2021: * genisoimage is officially marked "abandoned" and should not be used (time stamps will start break come 2028; I've fixed the bug but there's no genisoimage maintainer to update the program with the fix). See https://wiki.debian.org/genisoimage for end-of-life notice * As per that Wiki page, the official answer is to use xorrisofs, which yes has fixed (or never had) this "blank sector" bug * I have made my own fork of genisoimage, iso9660, which fixes this bug and the bug with post-2027 timestamps: https://github.com/samboy/iso9660 - Sam This behavior (or one very similar to it) appears to still be present, five and a half years later. The patch still appears to apply (albeit with considerable a offset) against current upstream SVN. I have not managed to find any indication of what the reason for adding these blank sectors is supposed to be. The code in question appears to date all the way back to the original import of mkisofs into Subversion, so there's no help there. Any chance of either getting this patch applied, or at least figuring out a reason why it would be a bad idea? > >
