From d095b465339b79929fd2adc25c0ab3598e80fd39 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 20 Dec 2013 19:28:14 +0100 Subject: blockdev: Move "file" to legacy_opts Specifying the image filename through the "file" option is a legacy option and should not be supported by blockdev-add (in that case, giving a string for "file" references an existing block device).
