Updated OpenBSD softraid install page
With their 5.1 release, OpenBSD has added support for placing the root filesystem on a softraid(4) device for the i386 and amd64 architectures. Additionally, the amd64 port supports booting the system from a kernel on the softraid device.
Previously, the way to provide system redundancy using software RAID was to use softraid for all of your filesystems except the root filesystem. The root filesystem would be copied to an identically sized partition on the second disk every night by the /etc/daily script. It was up to you to keep the boot blocks up-to-date.
Awesome. I’ve updated my Installing OpenBSD using softraid page. I’ll let you know how it goes.
