UX/Partitioner

From openSUSE

Reasons for change

• The current partitioning module in YaST is not suitable for beginners, although it is suitable for a sophisticated IT ecosystem
  • Hard to learn for non-experts
  • Non-intuitive wording and design
  • Too many buttons
• Simultaneous display of LVMs and partitions that are parts of LVMs
• Horizontal scrolling required for viewing details
• Modules for related tasks (iSCSI, LVM, Boot Loader) are separated from Partitioning Module

Conclusions

• Non-experienced users like Anne
  • should be fine with auto-partitioning
• Little-experienced users like Christian
  • should be able to deal with the basic partitioning
• Experienced users like Ihno
  • should be able to do all kinds of partitioning and LVM stuff
