From 564c0c4577dfd676472f4a41798909470fee6744 Mon Sep 17 00:00:00 2001 From: Hari Bathini Date: Mon, 2 Jun 2014 16:27:37 +0530 Subject: [PATCH] lsinird: Adding option "-m|--mod" to list dracut modules in the image This patch adds option "-m|--mod" to lsinitrd to list dracut modules in the image because sometimes having an option to only list the dracut modules in the image could be handy.
