[Bug 1022519] Re: UDF volume name wrong

[Dan Kegel]

Yup:

$ dd if=/dev/sr0 of=bug1022519.iso bs=514k count=1
$ blkid -p bug1022519.iso 
bug1022519.iso: LABEL="FSX DISK 1" TYPE="iso9660" USAGE="filesystem" 
$ dd if=/dev/sr0 of=bug1022519.iso bs=515k count=1
$ blkid -p bug1022519.iso 
bug1022519.iso: LABEL="UDF Volume" TYPE="udf" USAGE="filesystem" 

hexdump -C shows:
00080810  00 00 00 00 00 00 00 00  10 00 55 00 44 00 46 00  |..........U.D.F.|
00080820  20 00 56 00 6f 00 6c 00  75 00 6d 00 65 00 00 00  | .V.o.l.u.m.e...|

Windows gives 'FSX DISK 1' as the label.

I guess Windows prefers the iso9660 volume label for discs
of type CD001, and Wine won't be able to install that game unless blkid
does, too.

I've uploaded the first 515k to http://kegel.com/bug1022519.iso

Title:
  UDF volume name wrong

Status in “util-linux” package in Ubuntu:
  New

Bug description:
  Unity / Nautilus / udev display the volume name of a DVD as "DVD
  Volume" when it's really something else.

  The 'volname' command gets the volume ID of DVD volumes right:

  $ volname /dev/sr0
  FSX DISK 1                   

  but udev doesn't:

  $ udevadm info -q env -n /dev/sr0 | grep ID_FS_LABEL
  ID_FS_LABEL=UDF_Volume
  ID_FS_LABEL_ENC=UDF\x20Volume

  Nautilus and Wine and everyone else probably get the volume info from
  udev, so they get it wrong, leading to problems like games not
  installing (see http://bugs.winehq.org/show_bug.cgi?id=25558 )

  Where does the wrong name come from?
