From ba39ced8804765705f4c61a92db0fddb8d672c7d Mon Sep 17 00:00:00 2001 From: Richard Jones Date: Tue, 8 Jun 2010 16:04:01 +0100 Subject: [PATCH] file: Fix file command on /dev/VG/LV paths (RHBZ#582484). Previous commit 4df593496e116dfb635731c058b7627e81fc179c broke the "file" command on logical volume paths, since these are symbolic links. We *should* follow these (only). This inadvertantly broke virt-inspector too, which indicates that we need more regression testing in this area. Since carrying whole Fedora images around could make the distribution even larger than now, I'm not sure at the moment how to do this. Thanks to Matt Booth for diagnosing this bug. --- daemon/file.c | 7 ++++++- src/generator.ml | 2 +- 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/daemon/file.c b/daemon/file.c index a55c606..da899b6 100644 --- a/daemon/file.c +++ b/daemon/file.c @@ -581,8 +581,13 @@ do_file (const char *path) } } + /* Which flags to use?
