UDF file system minimum and maximum size limits are defined in terms of
numbers of file system blocks. So when resizing an existing file system
compute the byte size limits from the existing UDF file system's block
size. Alternatively when creating a new UDF file system use the
device's sector size as the multiplier instead.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
Those external tools were introduced in version 2.0 of udftools package
and can show or change UDF label, UDF uuid and can provide information
needed for counting total/free sectors.
Bug 792052 - Add support for changing UDF label/uuid and show disk usage
Make especially the Volume Identifier length limit code simpler to
understand and therefore easier to maintain.
Bug 784533 - Add support for UDF file system
UDF label is stored in the Logical Volume Identifier which has space for
either 126 Latin1 or 63 UCS-2 characters. For compatibility reasons
with older versions of blkid, the possibly truncated UDF label is also
stored in the Volume Identifier which only has space for 30 Latin1 or 15
UCS-2 characters.
Because versions of mkudffs prior to 1.1 damage the label if it contains
non-ASCII characters, make sure GParted does not call such versions of
mkudffs with a non-ASCII character label.
Bug 784533 - Add support for UDF file system
Add support for detecting UDF file systems and formatting hard disks
with revision 2.01 UDF file systems using udftools. Formatting optical
disks or any other media types is not supported yet. Changing label or
UUID after formatting is not supported as the tools do not yet exist.
