Kindly offline I received the hint: USE CVS UDFTOOLS Anybody here have a clue how I do that? Didn't kernelnewbies.org once contain a cvs tutorial? Revisiting now, all I find is an rtfm link? Pat LaVarre P.S. I had reported that the udf mkfs fails the udf fsck. By "the udf mkfs" I mean the udftools-1.0.0b2/mkudffs/mkudffs that `make` creates from: http://sourceforge.net/projects/linux-udf/ http://sourceforge.net/project/showfiles.php?group_id=295&release_id=74270 ... By "the udf fsck" I mean the udfct_1.0r2/src/udf_tester/udf_test that `make` creates from: http://www.extra.research.philips.com/udf/download/udfct_1_0r2.tar.gz -- Kernelnewbies: Help each other learn about the Linux kernel.
