The 'type' field is missing from the MBR in GEOM dumps.
This breaks (via libdisk) the FDISK partition editor in sysinstall.
See also
Type sysctl -b kern.geom.dumptxt
The ouput contains lines like the following:

1 MBR ad0s1 39999504384 512 i 0 o 32256

The line above should have a ' ty ' entry appended.
The breakage occurred after phk's 'Use default method initialization on geoms'
commit, dated 2004-08-08 06:49:07 UTC. I guess some parts of this commit should
be reverted.
