trinity good enough; +1 for using sh as interactive shell then; there's a thread I started at some point this year, regarding shell tips. If you have nice posix shell functions, aliases, tricks to share, then please go on :3. As for rc, I think it is on pkgsrc already. My intention is to test plan9port on NetBSD this summer. If you want I'll ping you as I get to it. My recommendation for plan9/9front is to run a cpu server on a raspberry Pi and connect to via drawtem (will log you into the rio windowing system). The SDF Plan9 Bootcamp for summer 2022 has just started: tons of 9front and NetBSD people out there.
