Jigdo is not suitable for making changes to the ISO which it reconstructs. (It is rather suitable for reducing the download effort with ISOs which are slightly changed towards an ISO which you already have. See the question "Files to scan:" of program jigdo-lite.) If you have files which you want to add to the ISO or if you want to replace existing files of the ISO, then maybe https://lists.debian.org/debian-user/2021/08/msg01170.html is of help, where i propose how to override a kernel and an initrd in the ISO. As mentioned in that post, there is the possibility that checksum lists or certficates let the booting system detect that existing files were altered. Your mileage may vary. Have a nice day :) Thomas
