I am working with several ways of doing it, and that's why I wanted to have a discussion about this. Ideally I'd want something like the MD autodetect code, so that the whole thing can be set up by the kernel at boot-time if the necessary drivers are compiled in (by reading the Medley superblock the same way it's done for 0xfe partitions). And if the drivers are modules, then use the drive mapper tools from userspace to set it up. This would be the most flexible solution, since it'd allow you to boot without an initrd if you wanted that, or to use the initrd and map the drives manually if you preferred that solution. Having autodetection at kernel level would make it possible to boot from a kernel on a floppy disk without initrd support, and in general make a system easier to set up. But the reason I wanted this discussion is to figure out the best way to go about it, and if there are some good arguments against autodetecting in the kernel I'll listen to them. // Thomas - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
