   I've been fiddling with NetBSD 0.9 for a few days now, and had a
   few questions about it.  Most are a result of my own ignorance,

No comment.

   1. What is this kernfs thing enabled by option KERNFS?

It is a file system that presents information about the kernel, like
load average, hostname, copyright notice, etc.  I mount it on /kern:

kern            /kern           kernfs  rw

   Is this some 4.4 BSD feature?

It has nothing to do with 4.4.

   2. Is there a libdbm for NetBSD?

It's in libc.

   3.  In the kernel currently, my system has the option MATH_EMULATE
   Does this mean that ALL my programs thus far that are using
   floating point are emulating it?

No.  It means that if you didn't have a floating point coprocessor,
the kernel will emulate it.  You don't need MATH_EMULATE if you have a
coprocessor.
