[rhel6-branch] Implement an option that lets anaconda name mpath devices by the wwid.
- From: Ales Kozumplik <akozumpl redhat com>
- To: anaconda-devel-list redhat com
- Subject: [rhel6-branch] Implement an option that lets anaconda name mpath devices by the wwid.
- Date: Thu, 16 Jun 2011 15:22:12 +0200
Adds a new option dialog to the filtering screen, with a checkbox. If user
unchecks this, /etc/multipath.conf is generated with user_friendly_names
set to "no". This will give all mpath devices names in the
/dev/mapper/<wwid> format, partitions are /dev/mapper<wwid>p1.
The setting defaults to using the friendly names.
Resolves: rhbz#709653
