That simple case wouldn't - Unless you knew that the machines this
manifest applied to both had at least 2 disks and that they were
compatible, but the device names arne't always the same
Derived manifests should help here
What is more useful for mirroring root is if AI could have logic to
pick a disk that is 'compatible' with 'boot_disk' and allow you to
reference it through 'boot_mirror'.
Interesting thought. What do envision the use case for this functionality ?
In addition (whether 'boot_mirror' is possible or not) having symbolic
names for 'disk0' through 'diskN' would also be useful in many cases.
Agreed, but that is part of vanity naming for disks which is outside
installs' scope. Admittedly this is something that is desired given that
disk names are getting very long.
