Title: fix bug in yast disk
openSUSE Distribution: Unconfirmed
Priority
Requester: Mandatory
Requested by: Andrew Joakimsen (joak0)
Partner organization: openSUSE.org
Description:
+ Summary Description yast-partitioner was updated for 11.3 and newer to
+ stop using CHS information as its primary partition alignment strategy.
+ The user interface was never updated to match. The user interface for
+ yast2-partitioner should be updated to allow the user to select legacy
+ CHS presentation and the more modern presentation units of sectors /
+ MBs / GBs or other units more appropriate to raid strides.
