I got all the way up to pkgsrc-wip setup with the NetBSD install and that's where my notes ended so that's where I paused for the night. I'll do that today and take notes.

one thing I found out: you can't have the 'log' and the 'discard' options both enabled on a FFS filesystem, which is unfortunate from a write amplification standpoint. good thing I got an industrial SD card, now I wish it was twice the size though to give that issue a bit more of a buffer.
