Requested by: Neil Brown (neilbrown) Partner organization: openSUSE.org Description: mdadm-3.3 (due to be released July 2013) will support md device named like "md_home" as well as the traditional "md4". However these names are likely to confuses installers and other system managers so they are disabled by default. To get full benefit from these we need to: 1) Make sure initrd scripts in mdadm package handle these names. 2) teach yast-storage to be able to use non-numeric names and not to be confused by them 3) update any system administration documentation 4) check any system monitoring tools to ensure they won't get confused.

Adding the line "CREATE names=yes" to /etc/mdadm.conf will cause names like "md_home" to be used in place of e.g. "md127" if a name was given when creating the array.
