I think the reason is to avoid unnecessary code duplication. device-mapper provides a generic method to do such things. Also the developers are heading towards removing code from the kernel that can be done in userspace. There are plans to remove partition detection from the kernel in 2.7 and move the detection and setup code to a userspace program (using device-mapper) which can be placed in the initramfs (so that the user won't notice any difference). Ataraid detection and setup could also be placed there later. If someone writes an ataraid detection and setup program in userspace it could be placed on an initrd. You can find the dmsetup tool in Sistina's device-mapper package. -- Christophe Saout Please avoid sending me Word or PowerPoint attachments. See http://www.fsf.org/philosophy/no-word-attachments.html
