At least on amd64 you don't need a special partition for the kernel. - Shell out of the installer. - sh /dev/MAKEDEV sd1 (etc). - Create the RAID partition on the physical disks, you don't need another partition there. - Use bioctl to create the softraid. - Run the installer normally and choose the softraid disk as the install destination.

The most obvious is that NAND flash devices have shorter lifespan than
hard disks. Imagine wearing out both devices simultaneously with the
RAID-1.
I think it's better to have a USB stick for /, /usr and dumprestore or
rsync it to the 2nd stick for redundancy. You should repeat this on
updates. You should keep /var, /usr/{obj,ports,src}, /home and any other
fs with frequent writes on the hard disks to extend the life of the USB
stick.

Thank you for sharing your wisdom, now i know what i *should do*, you
made it pretty clear. Have you considered three-way mirror? What do
you think about mounting filesystems read-only? Have you heard of NFS
and remote syslog? I'm sure you will grant us the mercy of knowing why
all these are not a good idea.

Re: AMD Zacate E350 (ASUS E35M1-M) dmesg/experiences?
I'm answering to myself here.. I finally got this motherboard and it's been running some services 24/7 for a week now, without problems. With 5.1-RELEASE. It's no server board (non-ECC ram, no IPMI, re(4) ) but I highly recommend it for cheap silent/low-power systems. A bit faster than Atoms, yet still no speed demon. But it has 6 SATA and supports up to 8GB of ram. And no cpu fan. My office is quiet again. # sysctl hw | grep temp hw.sensors.km0.temp0=51.50 degC hw.sensors.lm1.temp0=28.00 degC hw.sensors.lm1.temp1=39.00 degC Here's the dmesg: OpenBSD 5.1 (GENERIC.MP) #207: Sun Feb 12 09:42:14 MST 2012 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 8167038976 (7788MB) avail mem = 7935467520 (7567MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.6 @ 0xeaf40 (60 entries) bios0: bios0: ASUSTeK COMPUTER INC.
