What I did into my 48 disk machine was - create a separate 'zroot' pool
comprising of 20G gpt partitions carved of off 8 of those 48 disks
in mirror (yeah paranoia!!!) and boot of them. It works nice since I don't
waste too much space since it's a partition and gives me a lot of
What I have is simply the first vdev consisting of partitions that are 20G
compared to the rest of the vdevs. All those were organized in raidz2 = 6 x

Anyway ... something to consider in the cases when you don't have or you
want to have a dedicated bunch of disks for the operating system.
