Hi,
I have F8 and every time to I try to access remotely or locally NTFS filesystems that shared via Samba I get a warning (at the end of this mesage) from SELinux troubleshooter and can't access the share.
I have tried to mount the filesystem with different context's but none of them seem to do anything. The shares worked with previous version of Fedora (F7). I have tried to mount the NTFS volume doing the following to change it context:
* mount -t ntfs-3g /dev/sda1 /mnt/petteri-c -o context=system_u:system_r:smbd_t
* mount -t ntfs-3g /dev/sda1 /mnt/petteri-c -o context=system_u:object_r:smbd_t
* mount -t ntfs-3g /dev/sda1 /mnt/petteri-c -o fscontext=system_u:object_r:samba_share_t
and various other mount options such as defcontext= and changed the context=, fscontext=, and defcontext= parameter values.
But the context stays the same (ls --lcontext):
drwxrwxrwx  1 system_u:object_r:fusefs_t       root root 12288 2007-12-12 21:13 petteri-c

So how I am going tho get SELinux to allow Samba to share mounted NTFS filesystem? (Sorry about the newbie question :( and possibly bad english).
SELinux is enforcing/targetted and all the booleans that refer to smbd are checked allow from SELinux Administration.

Summary
    SELinux is preventing samba (smbd) "read" to <Unknown> (fusefs_t).

Detailed Description
    SELinux denied samba access to <Unknown>. If you want to share this
    directory with samba it has to have a file context label of samba_share_t.
    If you did not intend to use <Unknown> as a samba repository it could
    indicate either a bug or it could signal a intrusion attempt.

Allowing Access
    You can alter the file context by executing chcon -R -t samba_share_t
    <Unknown> You must also change the default file context files on the system
    in order to preserve them even on a full relabel.  "semanage fcontext -a -t
    samba_share_t <Unknown>"

    The following command will allow this access:
    chcon -R -t samba_share_t <Unknown>
