16.0-CURRENT main-n280279-b0e7b55a0e90 amd64.

There is following line in /etc/sysctl.conf (IIUC bsdinstall adds it
at install time if system is zfs-root).

vfs.zfs.min_auto_ashift=12

Today I noticed following error message is displayed when system is
booted.

sysctl: unknown oid 'vfs.zfs.min_auto_ashift' at line 9

And I get same error if I execute `sysctl vfs.zfs.min_auto_ashift`
from command line.

Does this mean vfs.zfs.min_auto_ashift is removed? If so, is it just
unnecessary any more or any alternative provided?

Best Regards,
