Updated dosfstools required

[Sitsofe Wheeler]

Description of the problem:
dosfstools v3.0.14 or later is required otherwise kernel warnings about DOS filesystems that have not been properly unmounted will never be silenced.

Steps to reproduce:
1. Start Raspbian.
2. Make sure all packages are up to date.
3. apt-get install dosfstools
4. sync
5. touch /boot
6. reboot -f
7. When the system has booted log in and run
dmesg | grep "FAT.*corrupt"
8. Run
umount /boot
dosfsck /dev/mmcblk0p1
mount /boot
9. Run
dmesg | grep "FAT.*corrupt"

Expected results:
No difference between the output of step 7 and the output of step 9.

Actual results:
An additional message is seen:
[ 14.887935] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
[ 111.596729] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

How reproducible is the problem?
It is reproducible every time.

Additional information:
The 3.8 kernel introduced a dirty bit check to see if DOS filesystems were unmounted properly but only dosfstools v3.0.14 or later clear this dirty bit (see https://lkml.org/lkml/2013/5/6/342 ).

I've installed dosfstools 3.0.26-3 after adding Jessie repo (sources.list entry: deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi), then I checked my corrupted vfat partition and rebooted the server.
This fixed FAT-FS error present in syslog [FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck].

Please make dosfstools 3.0.26-3 available in Wheezy repo to solve this issue.

Here is upstream patch for dosfstools: http://daniel-baumann.ch/gitweb/?p=software/dosfstools.git;a=commitdiff;h=ce2f8dc349a8a6b2c26d1b3892cc9b5f0408bd34

Someone on irc just pointed me to a targetted fix, applying and building now.

[peter green (plugwash)]

patched package is built and uploaded, Should be included in the next update run.

Peter:
Can you suggest what I did wrong with this bug report? It looks like it would have gone unfixed were it not for the unnamed IRCer...

[peter green (plugwash)]

As a general rule requests for new upstream versions are unlikely to be actioned. Targetted patches are far more likely to be actioned.
