Without the default configuration, logs from journald after more than a
year of daily driving the PinePhone were taking up ~2.6GB (out of 16GB
total internal storage), so having a time limit on systemd journal seems
necessary (e.g. shipping in mobile-tweaks-common, no need for it to be
device-specific).

It makes systemd ignore the power key, otherwise a simple press on it
would make it power down the system (especially important when running
the on-device installer).

I agree, libusbgx/gt is a better solution for the (not so) long term,
but there's still work needed before we can switch to it. I'm reasonably
confident this can be done during the current (bookworm) development
cycle, though.

That's a good point, we'll have to look into what's feasible in this regard.

This needs further evaluation but it might be illegal indeed, which is
why I won't be pushing to get those into Debian (at least until we make
sure it's legal, or find a way to extract those in a legally compliant way).

I already have access, you added me to the github org a while ago IIRC ;)
