Hi Mathieu, thanks for On Thu, 11 Jun 2020 16:24:48 +0200 Mathieu Othacehe wrote: > Here's a patch that disables HFS+ tree production, and the solves the > problem above. Thanks for the investigation and fix! What do you think about putting the comment into the source code? ;; Producing an HFS tree via "mbr_hfs" would fail if a directory has more than ;; 30720 files. The xorriso error message is: ;; xorriso : UPDATE : 434919 files added in 18 seconds ;; libisofs: FAILURE : HFS+ map nodes aren't implemented ;; libisofs: FAILURE : Too much files to mangle, cannot guarantee unique file ;; names. ;; So we use "mbr_only" mode to make sure that no HFS+ tree is generated. '(("MKRESCUE_SED_MODE" . "mbr_only"))))))) You can remove it from the commit message, or not (I would). In any case I'd rather not have to read the source code *and* all commit messages once some problem appears. I think it's as important to know what not to do as it is to know what is possible--especially for something as obscure as that. So I for one would welcome a comment in the source code of what already caused problems, even re-adding the problem as a comment. Otherwise LGTM!
