Ian:

Yes you are correct.... Maybe not the best method but I normally 
installkernel -
boot into single user mode - GELI attach, zfs mount -av, then 
installworld.

My boot volume is UFS, but many of the mount points are on zpools.

What would be the best way to test a new kernel without a full 
installworld
with new userland geli bits?

I currently don't have a way to backup my 35TB of data :-( and don't 
want to
lose anything..... and I need a back out method should a full 
installworld fail.

Thanks for you quick reply.
