The problem still exists, and there was never another solution proposed as far as I can see. (I posted a question about this a while back...) It is a big issue for people who happen to get a KOBJ_CHANGE uevent while their iSCSI session happens to be disconnected for some reason, because udev will end up removing the /dev/by-xxx links when it can't access the device. If there is no subsequent uevent when the device is available again, the links are never recreated. -Ewan
