Eh, you're basically looking at a small bit of device code that holds a
vnode to the new-utmp file, and has two small buffers exactly equal to the
size of an old-utmp entry and new-utmp entry. It's just a matter of
translating records one at a time.
Granted, a real userlevel fs abstraction would be more desirable....
