Subject: [PATCH 4/4] libkmod: add --with-modulesdirs configure option
Date: Tue, 16 Aug 2016 03:50:32 +0300
Message-ID: <20160816005032.28881-5-ab@fmap.me> (raw)
In-Reply-To: <20160816005032.28881-1-ab@fmap.me>

Let the user override default /lib/modules path. One can also
define several directories to be looked in order by specifying them
separated with a colon, like this:

./configure --with-modulesdirs=/lib/modules:/usr/local/lib/modules
---
 Makefile.am       | 1 +
 configure.ac      | 6 ++++++
 libkmod/libkmod.c | 2 +-
