It is smaller on x86:

[12:45pm] 139>ls -l /sbin/sysctl  /sbin/mount_kernfs
-r-xr-xr-x  1 root  wheel  14520 Feb 12  2017 /sbin/mount_kernfs*
-r-xr-xr-x  1 root  wheel  56288 Feb 12  2017 /sbin/sysctl*

Not only that, but if we are not using KERNFS during the installation
we should remove it from the kernels :-)

OTOH, I think leaving kernfs and changing sysctl to mount_kernfs is better.
