Names of RAID devices are built at boot time. It depends on /etc/mdadm.conf which should be part of the initramfs. Otherwise, consider the name random. > Either way, it won't boot again.

Linux software RAID is assembled once the kernel is up and running. Before, the system boot as usual on a single disk. Though, I'm not sure how mdadm will handle the disk change behind his back. Once the installed system is bootable, I suggest you to try to reinstall grub. This will be required at some point in time in the future to update it either way. > I'll stop wasting time > and follow your suggestion of installing on a single disk first, before I > mirror it thereafter. -- Nicolas Sebrecht
