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.

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
