Workstation install will overwrite HD partitions with RPMS on it? This is very stupid. I created an ext2 partition on the hard drive and copied the cd over (NFS didn't work, different bug). I had a separate partition for everything else. When I selected Worstation it warned me that it would overwrite everything, including the partition with the RPMS on it. Clearly the isntaller needs to prevent this if it is doing a HD installation.
This issue has been added to feature requests for future releases.
Should be fixed in the Pinstripe beta.
