Bug Description

If you have a device that only connects via wifi, using recovery mode will not be possible in current core20 images (currently testing 20200529.3 on pi). Once entering recovery mode, if you don't have ethernet connected, it will never find an IP. The only netplan config during the recovery session makes it clear why this is the case:
$ cat /etc/netplan/00-snapd-config.yaml
# This is the initial network config.
# It can be overwritten by cloud-init or console-conf.
    version: 2

            dhcp4: true
                name: "eth*"
            dhcp4: true

The fix for this will be Fix Committed in 2.46, but unfortunately this is not testable until we have a rebuild of the ubuntu-core-initramfs package to pick up snapd 2.46, and then the kernel snap needs to be rebuilt with that new version of ubuntu-core-initramfs. I expect this will be a few weeks but should be done before 1.0.
