I could barely read through this in 45 seconds, let alone type it and run it, 
and hope to not make typos at every step along the way.

SVM is the only volume manager that I can think of where I have to manually set 
up any metadata.  VxVM handles it automatically, ZFS handles it automatically, 
I think (although it's been awhile since I worked with it) AIX's LVM even 
handles it automatically.

> metainit d2 1 1 c1d0s0

Why do I need to include the number of slices?  Why can't it default to the 
number of command line arguments; which is what it should normally be (give me 
a -n # if I want to do something funky).  Why do I need to  provide the stripe 
width; again it should default (with a -w # if I want to go outside the norms). 
 These commands should be:

metainit -f d1 c0d0s0
metainit d2 c1d0s0
 
> metainit d0 -m d1
> metaroot d0

Why multiple steps (including after a reboot) to set up a mirror?  
metainit d0 -m d1 d2
should be enough, and the system should take care of things after the reboot by 
itself.  Actually, really nice would be something along the lines of 

metainit -r d0 -m d1=c0d0s0 d2=c1d0s0
(-r to show it is a root device)

Other VMs make some things easier, although not necessarily the specifics of 
the rootdisk.  Ever so, SVM still has much room for improvement.
