I've just upgraded to RC2 on Pi 3B+ from an earlier nightly, so used
the rebase instructions (had to manually add the GPG key, but otherwise was fine)
Now I don't have wifi at all - 'ip a' just lists eth0 an lo, nmcli can't see a wifi
device.
Most searches then go on to iwconfig/lsusb but these aren't in the base image
Are there any debugging instructions? Didn't see a smoking gun in dmesg/journalctl,
but not sure what to look for.
