It was ambiguous, I saw more than one valid interpretation.So let me get this straight, we can't use LVM with AMD64 under the 2.6
No, you completely misunderstood.
Which doesn't say we can use 64bit user tools with a 64bit kernel, but I assume this is what you mean.line either? Or we can if we use AMD64 [DM] libraries with a AMD64 kernel? DM = Device Mapper right?
You can't use Device Mapper with 32bit user tools on a 64bit kernel
right now.
