MOUNT_UDFS(1M)MOUNT_UDFS(1M)NAMEmount_udfs - mount a udfs file system
SYNOPSIS
mount -F udfs [generic_options] [-o specific_options]
[-O] special mount_point
mount -F udfs [generic_options] [-o specific_options]
[-O] special | mount_point
DESCRIPTION
The mount utility attaches a udfs file system to the file system hier‐
archy at the mount_point, which is the pathname of a directory. If
mount_point has any contents prior to the mount operation, these are
hidden until the file system is unmounted.
If mount is invoked with either special or mount_point as the only
arguments, mount searches /etc/vfstab to fill in the missing arguments,
including the specific_options. See mount(1M).
The udfs file system supports direct mounting of files containing the
file system as well as block devices. See mount(1M) and lofiadm(1M).
If special and mount_point are specified without any specific_options,
the default is rw.
If the directory on which a file system is to be mounted is a symbolic
link, the file system is mounted on the directory to which the symbolic
link refers, rather than on top of the symbolic link itself.
OPTIONS
See mount(1M) for the list of supported generic_options.
The following options are supported:
-o specific_options
Specify udfs file system specific options in a comma-separated list
with no intervening spaces. The following specific_options are
available:
m
Mount the file system without making an entry in /etc/mnttab.
remount
Remount the file system as read-write. The option is used in
conjunction with the rw option.
A file system mounted read-only can be remounted as read-write.
This option fails if the file system is not currently mounted.
-O
Overlay mount. Allow the file system to be mounted over an existing
mount point, making the underlying file system inaccessible. If a
mount is attempted on a pre-existing mount point without setting
this flag, the mount fails, producing the error device busy.

not super user
The command is run by a non-root user. Run as root.
no such device
The device name specified does not exist.
not a directory
The specified mount point is not a directory.
is not an udfs file system
The device specified does not contain a udf 1.50 file system or the
udfs file system module is not available.
is already mounted
The specified device is already in use.
not a block device
The device specified is not a block device. Use block device to
mount.
write-protected
The device is read-only.
is corrupted. needs checking
The file system is in an inconsistent state. Run fsck.
NOTES
Copy-protected files can be stored on DVD-ROM media using Universal
Disk Format (UDF). Reading these copy-protected files is not possible
as this involves an authentication process. Unless an authentication
process between the host and the drive is completed, reading these
copy-protected files after mounting and before the authentication
process, returns an error.
