Given there's been a lot of improvements to the Log File System in #NetBSD -current, here's how you can install a system to boot to an LFS root: * Download -current, e.g. https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/images/NetBSD-11.99.8-amd64-dvd.iso * Boot the installer and follow the steps as usual * When it shows you the final partition layout, use the arrow keys up to the partition displaying "FFSv2ea". Press return. * Modify its "type" to "4.4LFS", scroll down and select "OK". * Finish the installation and reboot. Pretty easy, right?
