From 5774bab43a1946acd8440ad759eb6cc26335e64c Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Sun, 23 Aug 2009 20:43:48 +0200 Subject: new package aufs2-util Since the aufs2 utilities seem to be available only via git, copy the current state into the src/ directory, with the samples/ directory removed. The files were intentionally left untouched, so custom changes are still kept in patch files for easier upstream sending. Using do-extract to copy the sources to the working directory has the downside of having to define an empty do-configure target (as this is not needed) but allows for using update-patches just like with any other package (which is not the case if the copying is done in a do-configure target). --- package/aufs2-util/src/auplink.c | 64 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 package/aufs2-util/src/auplink.c (limited to 'package/aufs2-util/src/auplink.c') diff --git a/package/aufs2-util/src/auplink.c b/package/aufs2-util/src/auplink.c new file mode 100644 index 000000000..1b48bea51 --- /dev/null +++ b/package/aufs2-util/src/auplink.c @@ -0,0 +1,64 @@ +/* + * Copyright (C) 2005-2009 Junjiro Okajima + * + * This program, aufs is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
