Re: NetBSD 7.0 on Mac LC III

John, thanks for your reply.

I'll check into it.  The /var/run/rc.log file seems to be pretty good
about logging what gets run.

Thanks, I'll check into hfsutils (I used to use hfsutils in GNU/Linux
before most distributions started supporting HFS).

ok, I'd be happy to test an optimized kernel.  The kernel that I
(mostly) optimized is 2190082 bytes, with a configuration file included
at the end of this message.  I probably need to learn how to
cross-compile on a faster machine...  Even with this kernel, boot time
is about 20 minutes, and it takes over a minute to login, with minimal
noticeable disk access.

thanks
