FreeBSD/mipsが某ルータで起動した

FreeBSD MIPS

http://svn.freebsd.org/base/user/jmallett/octeonをcheckoutしてきて、ブートローダの違いで動かん部分をゴニョゴニョした。
まぁ、殆どコメントアウトしただけなんだが。

Trying to mount root from ufs:cf0s1
ROOT MOUNT ERROR: 
If you have invalid mount options, reboot, and first try the following from
the loader prompt:

     set vfs.root.mountfrom.options=rw

and then remove invalid mount options from /etc/fstab.

Loader variables:
vfs.root.mountfrom=
vfs.root.mountfrom.options=

Manual root filesystem specification:
  <fstype>:<device>  Mount <device> using filesystem <fstype>
                       eg. zfs:tank
                       eg. ufs:/dev/da0s1a
                       eg. cd9660:/dev/acd0
                       This is equivalent to: mount -t cd9660 /dev/acd0 /

まーここまでくりゃ十分じゃないかね。
