 I think that this is a WONTFIX bug.
 
 It is well know, if less documented, that FreeBSD (gpt)zfsboot boot program
 tries to use a pool that contains a very first vdev seen by (gpt)zfsboot to load
 zfsloader or kernel.  You just have to take this into account.
 This behavior makes sense.  Trying to boot all pools may create more problems
 than it solves, e.g. if you have more than one pool that can be booted.
 
 You may try to work-around your problem using boot.config file.
 Place it in a root dataset of a pool that gets used by (gpt)zfsboo (tank, I
 presume) with the following contents:
 zroot:/boot/zfsloader
 
 P.S. Your example is incomplete, it doesn't show where root1, cache1, log1 come
 from :-)
