GRUB does its job but it appears the problem occurs when control is

At the GRUB menu edit the linux line to add systemd.unit=rescue.target
or systemd.unit=emergency.target.

systemd.unit=rescue.target gets stuck (just as before).

systemd.unit=emergency.target boots!  I can log in as root, but journalctl -xb gives nothing.  (And I don't know what else I can do then.  The system is read-only...)

You might get to a terminal to look at what the journalctl command and
/var/log/syslog reveal.

I tried a few of the grub commands in there, such as

  systemd.log_level=debug systemd.log_target=console console=ttyS0,38400



and

  systemd.journald.forward_to_console=1 console=ttyS0,38400



but no new messages seem to go to the boot screen.

I also tried

  systemd.debug-shell=1



but either tty9 looks exactly the same as the one from boot, or it is not switching.

Any suggestions would be appreciated...
