+# The default udev rules create two different by-id links for each storage
+# device on ESX, based the same serial number but with different prefixes.
+# The first is based on the bus type (scsi) and the second is a catch-all
+# "World Wide Name" (wwn). After migration, we import domain0 with the
+# "/dev/disk/by-id" path, but since udev runs asynchronously, we may end up
+# with a mix of wwn and scsi aliases. This causes problems when the DE tries to
+# match devices on the system to those in the pool, i.e. for removal.
+#
+# This moves the wwn links to the /dev/disk/by-id/wwn sub-directory, keeping it
+# available as a backup but limiting the /dev/disk/by-id namespace to one type
+# of id. We override the original rules in /lib/ with our new version in /etc/.
