[Bug 1217030] [NEW] udev IMPORT{builtin}="path_id" returns wrong value

[Christopher Johnson]

Public bug reported:

/lib/udev/rules.d/60-persistent-storage.rules has the line:
 ENV{DEVTYPE}=="disk", DEVPATH!="*/virtual/*", IMPORT{builtin}="path_id"

This function is suppose to return a unique "PATH" to a particular port that a device is plugged into.  Instead it is reporting the PCI address and a made up scsi ID:
  pci-0000:00:11.0-scsi-0:0:0:0

It reports the same value for all 5 active SATA drives in the system.
At the time of this report, one drive is removed for RMA, but all drives
were getting the same value.

udevadm info -a reports the following for the different drives:
  /devices/pci0000:00/0000:00:11.0/ata1/host0/target0:0:0/0:0:0:0/block/sda
  /devices/pci0000:00/0000:00:11.0/ata3/host2/target2:0:0/2:0:0:0/block/sdb
  /devices/pci0000:00/0000:00:11.0/ata4/host3/target3:0:0/3:0:0:0/block/sdc
  /devices/pci0000:00/0000:00:11.0/ata6/host5/target5:0:0/5:0:0:0/block/sr0

To verify I ran: 
  udevadm test /block/sdc
and then ls -l /dev/disk/by-path/
  pci-0000:00:11.0-scsi-0:0:0:0 -> ../../sdc
Running:
  udevadm test /block/sda 
results in:
  pci-0000:00:11.0-scsi-0:0:0:0 -> ../../sda
