I have a rather complicated setup. My disks are partitioned and the partitions are combined into either raid0 or raid1 arrays (software raid). I am not using dmraid or any sort of BIOS fakeraid. I would like to install Gutsy (yes, it must be Gutsy) on exactly one of these arrays (/dev/md3), without touching the others. AFAIK, I need the alternate CD, but it doesn't seem possible without nuking the whole disk. The live CDs (alternate or desktop + some additional fiddling) both see the raid arrays, but the installers refuse to let me install to them. Is this a known limitation? Is there a workaround? I think when I installed, I just used the (Xubuntu Gutsy) alternate CD, and I didn't care about nuking the drives because they were blank.
