They are no longer needed, having been replaced by a daemon for driverdomains which will run scripts as necessary. Worse yet, they seem to be broken for script-based block devices, such as block-iscsi. This wouldn't matter so much if they were never run by default; but if you run block-attach without having created a domain, then the appropriate node to disable running udev scripts will not have been written yet, and the attach will silently fail. Rather than try to sort out that issue, just remove them entirely. Signed-off-by: George Dunlap <george.dunlap@eu.citrix.com> Acked-by: Wei Liu <wei.liu2@citrix.com>
