I have described my !!!UNSUPPORTED!!! setup !!!WARNING, BLATANT
SELF-PROMOTION!!! here:

https://www.mimar.rs/blog/how-to-increase-openbsds-resilience-to-power-outages

So far I have two 6.5's on PCengine's apu2d4 (~20 6.2-6.4's). The only
"problem" I have since 6.4 is that I have to mount / rw when tcpdumping
because unveil does not like ro /etc.
