Hi Peter,

When I do manual zfs partitioning during installs, i follow the commands
used by the actual bsdinstall scripts (the ones that would have been
executed if I used the auto mode).

A copy of them can be viewed online here:

https://svnweb.freebsd.org/base/head/usr.sbin/bsdinstall/scripts/zfsboot?view=markup#l1313


Essentially the zpool create command needs to have:

zpool create -o altroot=/mnt -O compress=lz4 -O atime=off -m none -f zroot
raidz2 /dev/gpt/disk0 ...

Regards,
Ben
