Yes, you can compile a fs image into the kernel. This however will be static
and if you want editing then will need to use unionfs with mdmfs. tmpfs
cannot be used for this as it does not yet (to my knowledge) support unionfs.
My question is, how does one compile
of a single giant
kernel image and when boot, runs entirely in memory, the kernel in fact can't
read filesystems other than tmpfs because no filesystems are compiled in. It
appears all of this won't be possible in FreeBSD (looks like ufs is required)
but it appears I can get close to this.
Indeed, I'd
