I've put a new SD card image for Raspberry Pi Plan 9 onto the bell-labs.com repository, in /n/sources/contrib/miller/9pi.img.gz
I hope that mirrors like 9p.io can be updated soon to make the new image available. Apart from 3B+ support (including firmware files for the new wifi chip), this update should make some improvement on all Pi models: slightly faster usb and ethernet, corrections for a few very old Plan 9 bugs flushed out by the Go test suite, and some extra crypto support for better interoperability with modern hosts using ssh and hget.
