Description of problem:
When I eject a CD, I get the following SELinux warning. This behavior is new
starting with selinux-policy-targeted-3.3.1-51.fc9.noarch

Following this setroubleshoot output you will find an IRC conversation
transcript that might contain additional information to help solve this.

Summary:

SELinux prevented umount from mounting on the file or directory
"/media/.hal-mtab-lock" (type "mnt_t").

Detailed Description:

SELinux prevented umount from mounting a filesystem on the file or directory
"/media/.hal-mtab-lock" of type "mnt_t". By default SELinux limits the mounting
of filesystems to only some files or directories (those with types that have the
mountpoint attribute). The type "mnt_t" does not have this attribute. You can
either relabel the file or directory or set the boolean "allow_mount_anyfile" to
true to allow mounting on any file or directory.

Allowing Access:

Changing the "allow_mount_anyfile" boolean to true will allow this access:
"setsebool -P allow_mount_anyfile=1."

Fix Command:

setsebool -P allow_mount_anyfile=1

<glguy> When ejecting a CD I get the following selinux alert "SELinux prevented
umount from mounting on the file or directory "/media/.hal-mtab-lock" (type
"mnt_t"). "   Before I click "submit" on the bug-report, is this a known issue
(I didn't see it in the bug tracker)
<domg472> hi
<domg472> can you do cat /var/log/audit/audit.log | grep mnt_t | audit2allow -R?
<domg472> should paste only a few lines
<glguy> require {\n type mount_t;\n}
<glguy> #============= mount_t ==============\nfiles_manage_mnt_files(mount_t)\n
<domg472> f9?
<glguy> yes
<domg472> can you paste this line: 
<domg472> can you do cat /var/log/audit/audit.log | grep mnt_t

<domg472> thanks
<domg472> alright lets have a look
<domg472> first im going to see if this rule exists in policy:
<domg472> sesearch --allow -s mount_t -t mnt_t -c file
/etc/selinux/targeted/policy/policy.23
<glguy> Found 2 semantic av rules:
<glguy>    allow mount_t @ttr1392 : file { getattr mounton }; 
<glguy>    allow mount_t mnt_t : file { ioctl read getattr lock mounton };
