Most current ZFS best practices say to set min_ashift to 12 before creating vdevs. During install to the install device the installer is correctly doing this, but it is not made persistent after install.

Describe the solution you'd like
Either create /etc/sysctl.d/local.conf with vfs.zfs.min-ashift=12 or add it to trueos.conf

The only other solution is for me to make the change by hand, which I do, but users that are not aware of it will not have it set and if they create a vdev, they could wind up with ZFS sector size of 512 because default value of min_ashift is 9.
