ntfs3g -s option should be ignored, making autofs mounts failing

[Georg Grabler]

I've troubled some with mounting ntfs-3g file systems with autofs.

AutoFS passes the sloppy option (-s) to mounts, which it should not, since ntfs3g does not support it.

RedHat fixed it in mount.ntfs3g, see

Debian seems to want to import the upstream patch of autofs-5.10:
Reference: Debian (against autofs, not mount.ntfs3g)
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=773607
which includes the bugfix of autofs-5.10
http://www.spinics.net/lists/autofs/msg01018.html

Is it possible to get a fix for this in Ubuntu as the Fedora-Fix, or the upstream fix from autofs?

I did change the category from mount.ntfs3g to autofs, since there seems to be a debian bug referencing to a autofs fix which I found just after I submitted this - please apologize.

Workaround (sorry, UGLY), but it "works for now". May give you troubels updating in future :D.

cd /usr/sbin
cp -p ntfs-3g ntfs-3g.0
> ntfs-3g
vi ntfs-3g

#!/bin/sh
# fixes automount -s option that crashes ntfs-3g
line=`echo $@ | sed -e 's/-s//g'`
/usr/sbin/ntfs-3g.0 $line

I just re-built the package with the upstream patch, works properly.

Updating the bug, the fix was released a while ago with a new version of autofs.
