Is it possible to achieve this only with udev? I am trying to get 4 SATA
disks to be mounted based on the SCSI addresses, not the kernel default
name, to achieve the same mount point. The disks are removable. Disk
changes will only happen at boot time.

A sample drive
is /sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0

In the kernel log, I see (when sd_mod is loaded):

 msg_queue_insert: seq 759 queued, 'add' '/block/sda/sda1'
 udev_event_run: seq 759 forked, pid [3257], 'add' 'block', 0 seconds
old
 udev_rules_get_name: no node name set, will use kernel name 'sda1'
 create_node: creating device node '/dev/sda1'
 udev_done: seq 759 exit, 0 seconds old

When I make a udev rule, I thought I could use the pci ID. In my case, I
am trying:

SUBSYSTEM="block", ENV{ID_PATH}="pci-0000:00:1f.2-scsi-0:0:0:0",
SYMLINK="cameraB_2"

I would expect to see a symlink when the ID_PATH matches. But this does
not happen. I do not think this rule is being called. I have placed it
in a file called /etc/udev/rules.d/55-dpavue.rules.

I am also confused about this: 

When I load the ata_piix driver, I see things like this in the log:

 msg_queue_insert: seq 748 queued, 'add'
	'/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0'
 udev_event_run: seq 748 forked, pid [3223], 'add' 'scsi', 0 seconds old
 msg_queue_insert: seq 749 queued, 'add' '/class/scsi_device/0:0:0:0'
 udev_done: seq 748 exit, 0 seconds old
 udev_event_run: seq 749 forked, pid [3232], 'add' 'scsi_device', 0
seconds old
 udev_done: seq 749 exit, 0 seconds old

But is it appropriate for me to make a udev rule that acts at this time?
I tries this rule, with nothing happening (that I can see):

SUBSYSTEM="scsi", ENV{ID_PATH}="pci-0000:00:1f.2-scsi-0:0:0:0",
SYMLINK="cameraB_2"

But as udev does not make a /dev entry as a result of this call, I am
not sure what the SYMLINK would point it anyway.

Any useful suggestions are very welcome.

BTW, I am rebooting between changes of the rules - just to be sure. The
drivers are loaded after / is mounted. I load them with modprobe just to
be sure they are running when I think they are. If any of this makes any
difference...
