>Description:
The bootloader (at least on x86 and arm) has supported loading a ramdisk directly, without it being baked into a kernel module, for about a decade now.

The instructions for root-on-cgd at https://wiki.netbsd.org/security/cgdroot/ still describe the cgdroot.kmod kernel module, however, and it appears that the bare ramdisk isn't published in the releasedir anywhere.


>How-To-Repeat:
read https://wiki.netbsd.org/security/cgdroot/
>Fix:
1. cgdroot.fs (and zfsroot.fs) should be published in the releasedir.

2. https://wiki.netbsd.org/security/cgdroot/ should be updated to use cgdroot.fs.

3. Stretch goal: cgdroot and zfsroot should be combined, and support for https://github.com/riastradh/fidocrypt added (not necessary for closing this PR).
