Re: SRUing

I just got hit by this. I'm using a laptop that I added a second disk
to. That changed the root disk from /dev/sda to /dev/sdb. The rpool got
imported fine so boot succeeded. However silently bpool did not get
imported. A couple of kernel updates were done over /boot inside rpool
and were not reflected in grub. Effectively kernel became frozen at the
time when bpool failed to import. I dug through the zsys-setup file and
figured I'd add a couple of lines to convert partrpool and partbpool
from /dev/sdx to /dev/disk/by-partuuid. After I did that, I
opportunistically decided to check how the current source looks like and
I saw almost identical lines were added in

So yeah, even though this is an EXPERIMENTAL feature, it would be really
nice to avoid this gotcha.
