30  * Functions to convert between a list of vdevs and an nvlist representing the
31  * configuration.  Each entry in the list can be one of:
32  *
33  * 	Device vdevs
34  * 		disk=(path=..., devid=...)
35  * 		file=(path=...)
36  *
37  * 	Group vdevs
38  * 		raidz[1|2]=(...)
39  * 		mirror=(...)
40  *
41  * 	Hot spares
42  *
43  * While the underlying implementation supports it, group vdevs cannot contain
44  * other group vdevs.  All userland verification of devices is contained within
45  * this file.  If successful, the nvlist returned can be passed directly to the
46  * kernel; we've done as much verification as possible in userland.
47  *
48  * Hot spares are a special case, and passed down as an array of disk vdevs, at
49  * the same level as the root of the vdev tree.
50  *
51  * The only function exported by this file is 'make_root_vdev'.  The
52  * function performs several passes:
53  *
54  * 	1. Construct the vdev specification.  Performs syntax validation and
55  *         makes sure each device is valid.
56  * 	2. Check for devices in use.  Using libdiskmgt, makes sure that no
57  *         devices are also in use.  Some can be overridden using the 'force'
58  *         flag, others cannot.
59  * 	3. Check for replication errors if the 'force' flag is not specified.
60  *         validates that the replication level is consistent across the
61  *         entire pool.
62  * 	4. Call libzfs to label any whole disks with an EFI label.
