 Just a note that currdev would not affect the order of the pools in lsdev
 output.  It should affect from which pool the zpool.cache is loaded.
 
 Ah!  You probably need to issue unload command as well.  I keep forgetting that
 in default configuration loader loads up stuff before presenting its menu.  I've
 changed my loader.rc, so that nothing is loaded before the menu.
 
 But, yes, the best course of action seems to be to fix up zsplitroot right after
 splitting it off.
 
 Thank you for your persistence in testing and debugging!
