+Subject: [PATCH] rules: watch metadata changes in ide devices
+
+Formatting IDE storage does not trigger "change" uevents. As a result
+clients using udev API don't get any updates afterwards and get outdated
+information about the device.
+...
+root@qemux86-64:~# mkfs.ext4 -F /dev/hda1
+Creating filesystem with 262144 4k blocks and 65536 inodes
+Filesystem UUID: 98791eb2-2bf3-47ad-b4d8-4cf7e914eee2

+root@qemux86-64:~# ls /dev/disk/by-uuid/98791eb2-2bf3-47ad-b4d8-4cf7e914eee2
+ls: cannot access '/dev/disk/by-uuid/98791eb2-2bf3-47ad-b4d8-4cf7e914eee2': No such file or directory
+...
+Include hd* in a match for watch option assignment.
+
+Upstream-Status: Denied
+
+qemu by default emulates IDE and the linux-yocto kernel(s) use
+CONFIG_IDE instead of the more modern libsata, so disks appear as
+/dev/hd*. A similar patch rejected by upstream because CONFIG_IDE
+is deprecated.
