udfclient is suite of udf-related utils developed for NetBSD Available for debian-based distros and arch, but notably not for rpm-based distros according to https://repology.org/project/udfclient/versions can you download orig. tarball and patch it with attached patch and try to './configure / make' it on Linux box with normal {for us} gnu make? And run resulted udfclient from build dir? ./udfclient file.img (-W for writing) Also, can you try to compile my hack on newfs_udf from NetBSD current? just make in source tree.. might fail due to no configure at all. this is slightly different newfs_udf command, creates udf up to maximum revision 2.60 (with some limitations). My hack most likely will not work directly on optical drive - but it worked for me on small image file. Can you test it on large file too? both hacks already on my github (but I am not sure I uploaded files correctly via their webinterface)
