In my experience, the etcdist is generally a waste of disk space.  Most of
the usable utilities have had new versions released.  Lots of the rest is
special purpose software that has an audience, even though I don't know who
they are.

As far as I know (not a great distance), there is not now, nor is there planned
to be, a patchkit bridge between the two.

NetBSD installs on a few more disks than 386bsd, but not that many.

You are going to have to do some type of updates, if only to install a
new version when either 1.5 or 2.0 are released.  NetBSD is as close to
a 1.5 release as we have today (maybe not tomorrow, but today) and therefore
relieves the pressure to install and immediately patch.

I took a running 386bsd system and installed the NetBSD software over my
existing system.  It got kind of squirrelly around the part where the /bin
utilities were getting installed, but everything seemed to have worked out
OK in the end.  I didn't even bother with the install disk.  I just copied
everything over to the system and recompiled the kernel.  It was a more or
less straight-forward operation.

A note of advice to the world in general if you are going to attempt this
with a working 386bsd system:

SAVE YOUR /etc DIRECTORY!!!

The most time consuming part of installing NetBSD this way was going back
through the etc directory and fixing all of the 'system dependent' files
that I had already.  The master.passwd file was by far the most devastating.

I was lucky enough to have a backup on tape, but I really pity anyone that
tries this without having their passwd (and other) files on a backup 
somewhere.

Just what we need, another entrant in the 'my OS is better than you OS' 
contest.

Terrific :-(
