Hi, the use of xorrisofs/genisoimage option -f would convert those links into shared content data files, too.
Side note: Differing from my statement in bug #1031696, the current xorriso version does not complain about dangling symbolic links when -f is given. It silently includes them as symbolic links in the ISO. I will change the behavior so that a SORRY message is emitted in this case. With default settings of xorriso this will cause a non-zero exit value of xorriso. But processing will go on as with the current version. genisoimage -f emits a warning and does not include the dangling link in the result. I.e. the file is missing in the ISO. Have a nice day :) Thomas
