Subject: [PATCH v2] dracut: Verify multipath config_dir option
Date: Mon, 3 Feb 2020 17:00:34 +0530	[thread overview]
Message-ID: <20200203113034.GA19959@machine1> (raw)

The 90multipath/module-setup.sh file currently does not check the
dm-multipath config_dir option. This option in multipath.conf file is
used to specify a custom directory/path that contains the multipath
configuration files. It's default value is /etc/multipath/conf.d

Currently install function of module-setup.sh has hardcoded the above
path, but users could change it with config_dir option. So, adding
steps to read the path specified with config_dir option and add
these configuration files to the initial ram disk image.

Signed-off-by: Milan P. Gandhi <mgandhi-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

changes v2:
 - Removed awk/sed usage to get config_dir path
 - Added a check to verify if path specifed with
   config_dir is actual directory
