Description of problem:

I have several systems with SCSI Medium Changers (auto-loaders, tape libraries) attached. Up to and including Fedora 12 udev would create a "/dev/changer" symbolic link pointing to the specific /dev/sg* device.  After updating these systems to Fedora 13, these links are missing on all systems. 

Version-Release number of selected component (if applicable):

udev-151-9.fc13.i686, udev-151-9.fc13.x86_64

How reproducible:

always

Steps to Reproduce:
1. Boot a system with a SCSI Medium Changer attached
2. Check that the console log contains output similar to this:
...
ch0: type #1 (mt): 0x0+1 [medium transport]
ch0: type #2 (st): 0x1+7 [storage]
ch0: type #3 (ie): 0x0+0 [import/export]
ch0: type #4 (dt): 0xf0+1 [data transfer]
ch0: dt 0xf0: READ ELEMENT STATUS failed
ch0: INITIALIZE ELEMENT STATUS, may take some time ...
ch0: ... finished
ch 10:0:4:0: Attached scsi changer ch0
ch 10:0:4:0: Attached scsi generic sg6 type 8
...
3. Check if the /dev/changer link is there:
# ls -l /dev/chang*
ls: cannot access /dev/chang*: No such file or directory

  
Actual results:

Link is missing.

Expected results:

Normally, /lib/udev/rules.d/40-redhat.rules would detect that a SCSI type 8 device is there and create symlinks (in the example above, "/dev/changer" and "/dev/changer-sg6").
