Installation example in a usb disk using
http://9p.io/sources/contrib/miller/9pi.img.gz as host.
First apply usb_uas_and_close_ep.diff
on the host if you have problems with your usb disk or you are going
to connect and disconnect usb devices several times (e.g. using a kvm switch).

Edit cmdline.txt to something like this:
nobootprompt=local ifconfig= venti=tcp!127.1!17034 bootargs=local!#/dev/sdXX/fossil nvram=/dev/sdXX/nvram
And config.txt:
[...]
[pi4]
kernel=9pi4rc
[...]
You should now be able to boot from your usb disk.
