8.0-R failing to parse DHCP root-path or loader.conf/rc vars (Diskless NFS/PXE)

[Brian A. Seklecki (CFI NOC)]

All:


DHCP:
  option root-path "192.168.224.67:/export/tftpboot/root-db";

loader.rc:

  set vfs.root.mountfrom="nfs"
  set vfs.root.mountfrom.options="rw"
  set boot.nfsroot.path="/export/tftpboot/root-web"
  set boot.nfsroot.server="192.168.224.67"

loader.conf:

  mfsroot_load="NO"
  nfsclient_load="YES"
  init_path=/stand/sysinstall
  autoboot_delay=2

The kernel fails to mount / as RW with:

   "mount option <export> is unknown"

Then some mysterious file system that isnt' MFS and isn't NFS show up.

I don't think any of the docs out there are up to date, and from mailing 
list discussion, the syntax appears to have changed in 8.0

Anyone out there running a diskless config?
