Filesystem mount options (High Sierra and ISO9660)

Filesystem mount options (High Sierra and ISO9660)

When you add or modify a High Sierra or ISO9660 CD-ROM filesystem, you can set advanced options for this filesystem type. The Filesystem Manager supports the following options:

Convert Filenames to Lowercase
displays filenames in lowercase and suppresses any trailing period (.) characters. The default is to leave filenames in uppercase. If filenames have been recorded as POSIX® filenames, this option is not available.

Show Hidden Files
displays any hidden files when you mount the filesystem. The default is to not display hidden files.

Show File Version Numbers
displays file version numbers when you mount the filesystem. The default is to not display version numbers. If filenames have been recorded as POSIX filenames, this option is not available.

Default User
defines the default user for files and directories that are recorded without a final unrestricted extended attribute record (XAR). XAR is the optional data structure used within an ISO9660 format CD-ROM for recording file attributes.

If you set this option, you must use a valid user name or a valid user ID between 0 and 60000. If you do not set this option, the files are recorded with the user ID of the mount point for the filesystem.

Default Group
defines the default group for files and directories that are recorded without a final unrestricted XAR.

If you set this option, you must use a valid group name or a valid group ID between 0 and 60000. If you do not set this option, the files are recorded with the group ID of the mount point for the filesystem.

Default File Permissions
sets the permissions for files recorded without a final unrestricted XAR. Specify the mode in octal. See the chmod(C) manual page. The default permissions are set to 0555.

Default Directory Permissions
sets the permissions for directories recorded without a final unrestricted XAR. Specify the mode in octal. See the chmod(C) manual page. The default permissions are set to 0555.
