+UDF is the "Universal Disk Format" filesystem defined by OSTA, the Optical
+Storage Technology Association, and is often used for DVD-ROM, frequently
+in the form of a hybrid UDF/ISO-9660 filesystem. It is, however,
+perfectly usable by itself on disk drives, flash drives and other block devices.

+.B uid=
+Make all files in the filesystem belong to the given user.
+uid=forget can be specified independently of (or usually in
+addition to) uid=<user> and results in UDF
+not storing uids to the media. In fact the recorded uid
+is the 32-bit overflow uid -1 as defined by the UDF standard.
+The value is given as either <user> which is a valid user name or the corresponding
+decimal user id, or the special string "forget".

+If mode= is set the permissions of all non-directory inodes read from the

+.B dmode=
+If dmode= is set the permissions of all directory inodes read from the

+.TP
+.B bs=
+Set the block size. Default value prior to kernel version 2.6.30 was
+2048. Since 2.6.30 and prior to 4.11 it was logical device block size with
+fallback to 2048. Since 4.11 it is logical block size with fallback to
+any valid block size between logical device block size and 4096.

+For other details see the updated mkudffs.8 manpage, section
