Comment 7 for bug 2055333

I was able to confirm that https://github.com/canonical/netplan/pull/278 is the breaking commit with git bisect. I tried to bisect forward to 0.107.1 to see if I could find the behavior change back to working but I think my test setup is flawed or there's another factor at play here. I did spin up a fresh mantic install to verify that it does indeed work. I also verified that cloudinit is generating the same netplan files, and the generated systemd link and network files are also the same between mantic and jammy. I'll attempt to bisect from 0.107.1 back to 0.106.1 on mantic and see what that yields.
