UDF on disk drives
------------------

-Disklabels are not used, except for virtual partition "a" with
-2048-byte blocksize devices. MBRs are not used, the filesystem
-begins at LBA 0. Partition "c" should be used if writing directly
-to a drive instead of an image file. If the drive contains prior
-data, zero the leading sectors before use as shown in the first
-command below.
+OpenBSD disklabels are not used on storage media. OpenBSD will create
+an in-memory virtual "a" partition when natively mounting UDF filesystems
+read-only on 2048-byte block devices or images; see Interoperability with
+mount_udf(8) below.

This diff clarifies when a virtual "a" partition may be
used with udfclient images.

Thanks to Jens A. Griepen for bringing the matter to my
attention.
