Currently at milestone 7, I highly recommend you avoid openSUSE 11.3 if you plan to boot more than one OS.
I tried to install it on one harddrive (PATA/IDE mode), while preserving my RHEL 6.0-Beta install on another (SATA). I frankly fought with the SUSE installer, and it ended up nuking the LVM markings on the RHEL installation, and making it completely unbootable. It refused to leave the drive alone. Not content to get a full 250GB for itself, it wanted a chunk of the other. Apparently it has been scripted to aggressively pursue the swap partitions anywhere on the system, and be damned what it does to the other OS involved. On top of that, it was pretty much unusable once installed.
Novell, somebody needs to slap your developers.
To clarify: This is not a bug. This is a Microsoft-style casual disregard. I went through the detailed options on partitioning because the default proposal was unacceptable. When I got through, I double checked, reviewing what it was going to do. It looked okay, so I clicked “Next”. It then did what it first tried to do, and removed the LVM volume labels on the SATA drive. Plus, it refused to include the RHEL installation in the new Grub setup.
I’m sure they won’t admit to any such thing, but this smells like the good old days of, “It’s not done until Lotus won’t run!”
