[Bug 2147213] Re: [resolute] Unsupported platform 'Raspberry Pi 4 Model B Rev 1.2'.

[arQon]

Apparently I need to fix this tonight, so:

Obvious Problem #1 is that the posd upgrade simply rm'd the runlevelN
targets that used to be under /etc, without any notice, let alone
prompting. Kind of a problem when default.target is pointing at one of
them...

Anyway, that explains the boot failure, so the good news is it did at
least still load *a* kernel successfully - it just shat the bed in
userspace, which is hardly novel for systemd.

Obvious Problem #2 is that it's still booting kernel 6.8 instead of 7.0. No idea why that didn't change: there's no mention of any issues there in the logs, so I'm guessing maybe that was dependent on the installation of piboot-try that didn't happen?
I did see the update-initramfs run for 7.0 (still the traditional Many Times, I notice :P) during the upgrade, again without errors, so I just don't have much new information to offer.

The DTBs etc *look* reasonable at a quick skim, but I'm too rusty on
those to say they were obviously 100%, and I'm out of time. Sorry I
can't be more help rn: I'm going to have to reimage it back to noble,
and I expect it'll be a while before I feel inclined to try RR again
given how much work that systemd trainwreck is likely to be, but we'll
see.
