Hmm - isn't this what the "getbootfile()" in libutil is
made for?
I don't like either of these uses of the sysctl - IMHO there
should be an md layer of translation which is best done at
script level somewhere in /etc/rc/d/* (after all it is a
"machdep" sysctl), but _if_ we are going to fix things it
would be easier to fix at one place only.
