Besides changing autodetected device names from /dev/mdX to /dev/md_dX I currently can not see any other difference, save lilo being unable to work with them. Normal raid devices can be partitioned without hassle, unfortunately in-kernel autodetection of nested raid arrays does not work (talking about raid0 over raid1 here, not raid10), but that is more or less understandable. Another quick question: What is the status of in-kernel autodetection vs initramfs based one? As I could gather from various sites it seems initramfs is preferable, but what does that mean for in-kernel detection? Is it slowly being phased out? Tnx for info, b.
