Created attachment 335715 [details] screenshot: Partition 1 does not end on cylinder boundary Description of problem: problem with partition layout (screenshot attached) Version-Release number of selected component (if applicable): boot.iso from 17.03.2009 anaconda-11.5.0.31-1.i586.rpm How reproducible: Steps to Reproduce: 1. install in a VM via boot.iso 2. 3. Actual results: Expected results: Additional info:
We are aware of the fact that we are not creating partitions on cylinder boundaries at this time. We are interested in determining if it is actually necessary or if it is just something that people do out of some vague fear. If you are seeing any negative consequences, or know of any, please let us know.
Head Scratch up to now my "vague fear" only is that we/you will start to see this or similar bug reports from people are able to do "fdisk" on c-l-i... close this one !
As you wish.

Hi, If you are not using cylinder boundaries, what do you use to create partitions ?

We use sectors. We align them according to the alignment data provided by the kernel for each block device.
