RAID sets can also be auto-configured at boot. To make a set

Note that since kernels cannot (currently) be directly read from RAID
components or RAID sets, some other mechanism must be used to get a
kernel booting. For example, a small partition containing only the
secondary boot-blocks and an alternate kernel (or two) could be used.
Once a kernel is booting however, and an auto-configuring RAID set is
found that is eligible to be root, then that RAID set will be
auto-configured and used as the root device. If two or more RAID sets
claim to be root devices, then the user will be prompted to select the
root device. At this time, RAID 0, 1, 4, and 5 are all supported as
root devices. Multi-layered RAID devices (such as a RAID 0 set made
up of RAID 1 sets) are
.Ar not
supported as root devices or auto-configurable devices at this point.
(Multi-layered RAID devices
.Ar are
supported in general, however.)
