Explain the usage of mkisofs to create UDF/ISO-9660 hybrid filesystem in a single pass
Jul 24, 2015 at 15:51 comment added starfry The mkisofs tool has a -udf option that will create a udf filesystem. It actually creates a hybrid that is UDF and ISO9660 plus, optionally, rockridge and joliet (if the -r and -J options are also given).
Jul 25, 2013 at 20:42 comment added sciurus To prevent the "readonly mount" error, When passing the media type to mkudffs use dvdrw instead of dvd.
Feb 25, 2013 at 9:33 comment added Dyno Fu @Oleg2718281828, I run into the same problem on Ubuntu 12.04. And following the instruction in /usr/share/doc/udftools/README.Debian.gz, I can create a data udf file.
Oct 15, 2012 at 6:45 comment added Oleg2718281828 Doesn't work on Ubuntu 11.04! I can follow the "general data" recipe to the point where I can mount the *udf file. However, I can not write in the udfimage directory. The error I get is "Read-only file system" (even though mount lists it as rw)

apparently -t udf needs to be specified in latest kernel version, otherwise file is mounted ro

remove use of sudo for mkudffs (not necessary); ref manpage for other media types; explain use of sparse files; ref wikipedia for DVD media sizing
Mar 5, 2012 at 21:22 comment added jmtd @polemon: truncate and mkudffs both create sparse files by default if your filesystem uses them: so go ahead and create a 4.4G image, it won't occupy that on disk unless you fill it.

Aug 1, 2011 at 9:30 comment added user8909 @polemon: you could use du for example, to determine the size of the directories to be copied and then make the image this size, but I don't know of a single tool that does this. You are right we are not supposed to have discussions in the comments but I have edited the answer to include mention of this.

Simplified process since losetup is not necessary, mentioned sizing options
Jul 31, 2011 at 6:55 comment added polemon I don't want to morph this into a discussion, but with genisoimage I don't have to care about the image size, genisoimage figures out the size itself, when creating it. But when dealing with UDF, I make a UDF image beforehand and then fill it. More often than not, the size doesn't fit, and I need to create another image. Is there a tool, that can create the image and fill it with the files specified, while keeping the size of the image minimal? Keeping the image size minimal, facilitates putting the image online, etc.
Jul 30, 2011 at 8:47 comment added user8909 @polemon - yes, you just burn the image as normal. I haven't tried Blu-ray myself, but I imagine the process is very similar. And good find with mkudffs, I had no idea you could use it directly on the blank file and this makes the process a lot easier.
Jul 30, 2011 at 5:07 comment added polemon I just noticed, you can use mkudffs directly on a file: mkudffs --media-type=dvd test.udf
Jul 29, 2011 at 16:26 comment added polemon Nice! And I believe, I burn that image to DVD just as I burn ISO images to CDROM, right? With BluRay this procedure is the same, I'm guessing?

Added instructions for general data using loopback
Jul 29, 2011 at 10:48 comment added polemon OK, but I want to use UDF just for general data, not just for video. Since UDF is a filesystem, it can be used on CDROM as well.
