Hi Rebecca,

Thank you for your quick response. With your entry the booting behaves 
exactly the same as with the previous entry. But I solved the problem 
thanks to a response from Emrion on the forum. The issue was that the 
bootfs wasn't setup (I used bsdsysinstall to install FreeBSD but had to 
partition by hand due to other partitions being present on the disk - 
and so the script skipped any bootstrapping setup). So after

zpool set bootfs=tank7/ROOT/default tank7

the system now boots correctly (with either UEFI boot entry).
