I had hoped I made it clear earlier; vfs.root.mountfrom is a kernel
environment variable, not a sysctl variable. You can read the kernel
environment from the kern.environment sysctl in a slightly non-obvious
fashion: get the oid for kern.environment (two values), then add one
more value to the oid and iterate it from 0 until you receive ENOENT.
Each read will return one string from the kernel environment.
You're probably right in that it should be exposed in the sysctl space,
yes.
