Hello,
I'm trying to optimize NetBSD 7.0 on a Mac LC III. The LC III has 36 MB memory and no FPU. NetBSD 7.0 (everything except for X) was installed successfully on an external SCSI disk using the traditional method.
1) It takes about 2-3 days to compile a new kernel. Whether using the default or a customized kernel, the system takes about 20 minutes to run through all of its rc scripts during boot, even though almost everything is disabled in /etc/rc.conf. I see in /var/run/rc.log that many scripts are run; is there any automatic way to create a single script with just the things that I need based on the settings in /etc/rc.conf? I could create such a script manually, but I don't want to miss anything important.
2) When configuring a new kernel, is it sufficient to comment out entries, e.g.:
...
#options M68040
options M68030
#options M68020
...
Or should I use "no options ..." instead?
...
no options M68040
options M68030
no options M68020
...3) Are the FPSP and FPU_EMULATE options needed for a 68030?
4) Some commands (such as "ps aux") take a long time (minutes) to run. Is that normal? Here's the output from "ps aux" (I'm currently compiling a kernel and left those lines out):
USER PID %CPU %MEM VSZ RSS TTY STAT STARTED TIME COMMAND
root 0 0.0 78.1 0 28776 ? DKl Tue07AM 34:51.88 [system]
root 1 0.0 2.3 3616 820 ? Is Tue07AM 0:02.24 init
root 727 0.0 2.8 6060 1008 ? Ss Tue07AM 0:19.48 /usr/sbin/syslogd -s
root 1835 0.0 2.2 3668 804 ? Is Tue08AM 0:01.00 /usr/sbin/inetd -l
root 1966 0.0 2.9 3580 1052 ? Is Tue08AM 0:23.48 /usr/sbin/cron
Is it normal for the "[system]" RSS to be what appears to be the amount of available memory?
5) Several years ago I used NetBSD 1.4 on an SE/30, and I don't remember it being as slow. Unfortunately, SE/30s seem to self-destruct over time, and I no longer have one available for testing. Would it be better to just use NetBSD 1.x on the LC III? My main reason for wanting to use 7.0 was to have a more modern gcc and related tools.
6) Are there any plans to support HFS filesystems in addition to HFS+? To more easily move files to NetBSD, I had to install Mac OS 8.1 just so I could create an HFS+ volume. (I boot into NetBSD from Mac OS 7.6.1.)
thanks for any information
