This worked perfectly on the first try. (if anyone is interested, I can post my commented command series for that, but it's just a mix of the available tutorials on the web..). I'll be glad do give the zfs-only solution a new try. Had the same impression, that the loader was involved in the problem, but had no env at hand to build a -CURRENT right away... (I did, in fact, repeat the dd-steps a zfsboot bootloader from a recent 8- snapshot iso... with the results being the same as before...). Sidenote: I encountered a few panics when using rsync with the HAX flags enabled (rsync -avxHAX from UFS to ZFS). I'll try to figure out which one of the flags caused it... (Hard links, ACLs, or eXtended attributes..). Never had even the slightest problem with rsync -avx. Thanx for posting me your loader, I'll try with this tomorrow night!
