Just to add some information.

Looking at the bsdinstall->zfsboot script, ashift is set by "sysctl
vfs.zfs.min_auto_ashift=12" and not by "zpool set ashift=12 zroot", but I think
it would still be clearer if both variables were set. 
So definitely not a bug.

Am I correct in understanding that min_auto_ashift is the system-wide default
for "zpool create", but you can still override it with "zpool create -o
ashift=9" ?
