Re: git: 87a7b35f04b6 - main - bsdinstall: fix vfs.zfs.vdev.min_auto_ashift oid

(...)

Maybe this need to be fixed somehow because values are different:

% sysctl -a | grep ashift
<118>sysctl: unknown oid 'vfs.zfs.min_auto_ashift' at line 9
<118>sysctl: unknown oid 'vfs.zfs.min_auto_ashift' at line 9
<118>sysctl: unknown oid 'vfs.zfs.min_auto_ashift' at line 9
<118>sysctl: unknown oid 'vfs.zfs.min_auto_ashift' at line 9
<118>sysctl: unknown oid 'vfs.zfs.min_auto_ashift' at line 9
vfs.zfs.vdev.max_auto_ashift: 14
vfs.zfs.vdev.min_auto_ashift: 9
vfs.zfs.vdev.file.physical_ashift: 9
vfs.zfs.vdev.file.logical_ashift: 9
