That would be very nice, but the docs for pinning stuff is damned near a
secret, and involves (apparently) more ways than
the /e/a/preferences.list. I've managed to do it but can't recall how I
did it 4 years later. And I've done it on a rpi4 to lock in the
preempt-rt kernel I built and installed, but
rpi4.coyote.den/etc/apt/preferences.d is empty. So I'm zip help, sorry.
