F13: Unable to mount ntfs-3g, option: 'context=' no longer supported?

[Dan Thurman]

Some weeks ago, I have installed F13 on a system
and for some time, I have successfully mounted all
of my partitions as defined in my fstab file.

But today, I have rebooted this F13 system and for some
reason, it was unable to mount any of my ntfs filesystems
with an error message: "ntfs-3g-mount: Invalid argument",
for each ntfs partition defined in the /etc/fstab.

I can manually mount a ntfs-3g partition to /mnt,
I can see the contents and context and every thing
seems fine for this ntfs partition.

I did:

# mount /dev/sdaX /mnt  (it works)
# mount  -t ntfs-3g /dev/sdaX /mnt (it works)
# mount  -t ntfs-3g -o context="system_u:object_r:samba_share_t:s0"
/dev/sdaX /mnt (breaks!)

The problem is that the context=XXX option is no longer recognized, or
so it seems.

The fstab entry breaks as well for ntfs:

LABEL=Ap1WD1 /md/Ap1WD1 ntfs-3g
context="system_u:object_r:samba_share_t:s0"     0 0


So what is the problem?

Try it without the :s0 at the end - maybe the system has got into
non-MCS(?) mode.

I think I figured it
out...

For /etc/fstab, the original line was:

LABEL=Ap1WD1 /md/Ap1WD1 ntfs-3g context="system_u:object_r:samba_share_t:s0" 0
0

And now should be:

LABEL=Ap1WD1 /md/Ap1WD1 ntfs-3g context=system_u:object_r:samba_share_t:s0,defaults 0 0


The difference is, adding ',defaults' to the end of the context option
is now required. Notice that quotes are not necessary, it makes no
difference, AFAIK

I am able to get the ntfs filesystems mounted and the selinux
context is correctly applied to the ntfs mounted filesystems.

Open a bugzilla.  I beleive fuse was doing some work to make context
mounts work.
