Right. You'd need a post-installation initrd. The installer will install
the kernel package into the target filesystem and this produces a suitable
initrd in /boot. (But note that this is inaccessible from the MacOS
bootloader unless your /boot partition is formatted with HFS).
The real mystery here is the two minute pause:
[ 2.560000] random: fast init done
[ 133.760000] random: crng init done
[ 146.040000] Block layer SCSI generic (bsg) driver version 0.4 loaded (major
252)
My first thought was that there isn't enough entropy before device drivers
load. But I no longer think that this issue is related to the RNG at all,
because when I boot that kernel in QEMU, I get a completely different
result. (See attached log.) Weird.

It seems that the old ADB keymap got enabled ("2==3" maps to "root"). This
page has some explanation.
https://www.debian.org/ports/powerpc/keycodes
I guess a systemd unit loaded a bogus keymap with ADB keycodes. We need to
"get rid of the ADB keymap" like that document says. I'll have to perform
a full installation to figure out how to do that.

Yes, it takes forever.
