[Bug 1012081] Re: util-linux needs updating to 2.21+

[Martin Pitt]

Assigning to LaMont, as he kindly agreed to update the package.

This is also needed to fix wipefs to properly clean up VFAT devices.
With the current version you need to call it three times before it
succeeds. This is reproduced with the udisks2 test suite, and with these
manual commands:

# empty initially:
$ sudo modprobe scsi_debug
$ sudo blkid -p /dev/sdb

# create FAT:
$ sudo mkdosfs -I  -n testvfat /dev/sdb 
mkdosfs 3.0.12 (29 Oct 2011)
$ sudo blkid -p /dev/sdb
/dev/sdb: SEC_TYPE="msdos" LABEL="testvfat" UUID="CA17-02B3" VERSION="FAT12" TYPE="vfat" USAGE="filesystem" 

# wipe it:
$ sudo wipefs -a /dev/sdb
8 bytes were erased at offset 0x36 (vfat)
they were: 46 41 54 31 32 20 20 20

# not empty yet!
$ sudo blkid -p /dev/sdb
/dev/sdb: SEC_TYPE="msdos" LABEL="testvfat" UUID="CA17-02B3" VERSION="FAT12" TYPE="vfat" USAGE="filesystem" 

# wiping once more is still not sufficient
$ sudo wipefs -a /dev/sdb
1 bytes were erased at offset 0x0 (vfat)
they were: eb
$ sudo blkid -p /dev/sdb
/dev/sdb: SEC_TYPE="msdos" LABEL="testvfat" UUID="CA17-02B3" VERSION="FAT12" TYPE="vfat" USAGE="filesystem" 

# wiping a third time finally works:
$ sudo wipefs -a /dev/sdb
2 bytes were erased at offset 0x1fe (vfat)
they were: 55 aa
$ sudo blkid -p /dev/sdb

$ sudo rmmod scsi_debug

Title:
  util-linux needs updating to 2.21+

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

Bug description:
  Applications in the default desktop - specifically gnome-disk-utility
  - depend on behaviour only introduced in util-linux 2.21+.
  Specifically if you select "Show in user interface" in mount options,
  it adds the mount option "x-gvfs-show" to the mount options in
  /etc/fstab. Mounting of this mount point then fails because the option
  is unrecognised.

  Also reported bug from the other point of view in bug #1011257
