Feature changed by: Stefan Hundhammer (shundhammer) Feature #318196, revision 5 Title: Redesign YaST Storage Code Requested by: Arvin Schnell (aschnell) Partner organization: openSUSE.org Description: The structure of the target-map (holding almost all storage data in YaST) is outdated and not documented. Adding new features, e.g. use whole disk for filesystem, bcache, dm-cache or switching to and from partitions on MD RAID, is difficult and error-prone. Thus a redesign is required to be prepared for new features and make the software more robust. During hackweek I evaluated using the boost graph library for libstorage. The result was announced and is explained, see references. I consider the redesign to be mandatory but not for a specific version (although as soon as possible). Note: This feature is about a redesign, new functionality must by requested as individual feature requests.
