fs-udf.so

Universal Disk Format (OSTA-UDF/ECMA-167) filesystem support

Syntax:

driver ... udf udf_options ... &

Runs on:

Neutrino

Options:

Where driver is one of the devb-* drivers, and udf_options is one or more of the following, separated by commas:

fileset=num

The File Set number to mount; the default is 0.

gid=group

The group ID to use for files with no specified group. The default is 0.

hidden=hidden_mode

Specify what to do with "hidden" files. The hidden_mode can be one of:

• ignore -- ignore the hidden files; they don't appear in the filesystem.
• show -- (the default) show hidden files in the filesystem as normal files.
• dot -- show hidden files in the filesystem with a dot (.) prefixed to their names.

info=path

The name of the filesystem metadata directory. The default is .info..

uid=user

The user ID to use for files with no specified owner. The default is 0 (root).

verify=level

How much of the UDF tag content (tag version, tag location, header checksum, and/or data CRC) to verify; one of the following:

• none
• tag -- all except the data CRC
• all
• ?tag
• ?all (the default)

Some UDF authoring utilities write incorrect tags, so it might be necessary to relax the verification if problems are observed. If you specify an option with a leading question mark (?), fs-udp.so consults an internal blacklist of known bad utilities and automatically skip all checks; otherwise it operates at the level given after the question mark.

volume=num

The Primary Volume number to mount; the default is 0.

In addition, you can specify any of the filesystem options described for io-blk.so.

Description:

The fs-udf.so shared object provides support for UDF (OSTA-UDF/ECMA-167) filesystems. It's automatically loaded by the devb-* drivers when mounting a UDF filesystem.
