6 udfs - universal disk format file system
7
9 The udfs file system is a file system type that allows user access to
10 files on Universal Disk Format (UDF) disks from within the Solaris
11 operating environment. Once mounted, a udfs file system provides stan‐
12 dard Solaris file system operations and semantics. That is, users can
13 read files, write files, and list files in a directory on a UDF device
14 and applications can use standard UNIX system calls on these files and
15 directories.

18 Because udfs is a platform-independent file system, the same media can
19 be written to and read from by any operating system or vendor.

21 Mounting File Systems
22 udfs file systems are mounted using:
23
24 mount-F udfs -o rw/ro device-special

28
29 Use:
30
31 mount /udfs
32
33
34
35
36 if the /udfs and device special file /dev/dsk/c0t6d0s0 are valid and
37 the following line (or similar line) appears in your /etc/vfstab file:
38
39 /dev/dsk/c0t6d0s0 - /udfs udfs - no ro

44 The udfs file system provides read-only support for ROM, RAM, and
45 sequentially-recordable media and read-write support on RAM media.

48 The udfs file system also supports regular files, directories, and sym‐
49 bolic links, as well as device nodes such as block, character, FIFO,
50 and Socket.

56 Invalid characters such as "NULL" and "/" and invalid file names such
57 as "." and ".." will be translated according to the following rule:
58
59
60 Replace the invalid character with an "_," then append the file name
61 with # followed by a 4 digit hex representation of the 16-bit CRC of
62 the original FileIdentifier. For example, the file name ".." will
63 become "__#4C05"
