H A Dmd.4diff 5cf10fb96a24a673f0ddbbcda322e0eb7af14dae Wed Dec 20 19:23:22 CET 2017 Ian Lepore <ian@FreeBSD.org> Add a new kernel config option, MD_ROOT_READONLY, which forces on the
MD_READONLY flag for the md device automatically instantiated during
kernel init for an mdroot filesystem.

Note that there is specifically and by design no tunable or sysctl
control over this feature. Without this option, you already have control
over whether the mdroot fs is writeable using vfs.root.mountfrom.options
from loader(8), the root_rw_mount rcvar, and by using "mount -u[rw] /"
or equivelent on the fly. This option is being added to provide a way
to make the mdroot fs truly immutable before userland code begins running.
