Any attempt to boot a system with the pool in a different location will lead to a panic in vfs_mountroot.</p>
<p>This is an annoyance if you ever need to move a system disk from one machine to another, as the paths will likely change. Or if you change the mode of some controllers which has the same effect.</p>
<p>It also makes life very difficult if you're trying to bring up illumos on AWS. There, booting from "media" isn't really an option, and you don't have any console access to work around it. So you either need to start from an existing AMI with a working root pool, or build the image using Xen set up exactly the same way AWS is. Fortunately you only need to solve this once, but it's something I would rather not have had to solve at all.</p>
