Chris Cappuccio created flashrd https://www.nmedia.net/flashrd/flashrd-faq.html I am not sure how useful it is these days as tmpfs was disabled in the Fall of 2016 https://marc.info/?l=openbsd-misc&m=146980890627188&w=2 You also have https://stable.rcesoftware.com/resflash/ Once upon a time people used Flashboot https://www.mindrot.org/projects/flashboot/ Honestly even SMART capable SSDs are so cheap these days that the only reason I can see you running OpenBSD from a USB Flash drive is to use something like Ubiquiti Networks EdgeRouter LITE. I do use Octeon port of OpenBSD on multiple firewalls around our lab but it is all generic kernel https://www.openbsd.org/octeon.html and I am not very concern that the USB will fail due to the excessive read and write.
