I have the impression (didn't check though) that the pool is made available by 
just setting some information in its main superblock or something alike (sorry 
for the imprecisions in ZFS jargon). I understand the OS knows which pool/fs it 
wants to mount onto /. It also knows that the root filesystem is ZFS, so it 
could in theory be able to import the pool at boot, I suppose. So I wonder if 
the OS could prompt the user on the console to import the pool or even use some 
(additional) boot options to instruct it to either import the pool without 
asking or reboot without panicking (e.g. -B 
auto-import-exported-root-pool=true/false). I guess this would be an RFE rather 
than a bug. Any thoughts on it?

Off-topic question, but I cannot resist. What is "FMA-style knowledge articles"?
