NAME

6       udfs - universal disk format file system
7

DESCRIPTION

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.
16
17
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.
20
21   Mounting File Systems
22       udfs file systems are mounted using:
23
24         mount-F udfs -o rw/ro device-special
25
26
27
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.
46
47
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.

NOTES

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"
