An alternative that occurred to me later is putting console=tty0 on

mean debian-installer wouldn't run on serial consoles when launched

D-I runs on each available console. So you would get it on tty0 and
on ttyAMA0.
I'm seeing different behaviour on a QEMU VM and my chromebook when I add
console=tty0 to the kernel commandline, where the /proc/consoles
contents end up being:
| "console=tty0" | no console arg |
-----------+------------------+----------------+
QEMU VM | tty0 and ttyAMA0 | ttyAMA0 only |
-----------+------------------+----------------+
Chromebook | tty0 only | ttyS2 and tty0 |
-----------+------------------+----------------+
The essential difference between the two devices is:
- the QEMU VM has a ACPI SPCR table for the serial port
- the chromebook has a "chosen stdout-path" dt node for the serial port
I expect the installer will launch on both consoles in the QEMU VM as
you said, I momentarily forgot that ttyAMA0 persists on the VM even with
"console=tty0". What I meant is it will only launch on tty0 on the
chromebook, where ttyS2 might be working but won't be in /proc/consoles
(if that makes sense).
