boot/init sequenze into rescue mode

[TomZa]

Hi all,

Problem: I messed up my getty@tty1.service file
                Now pinetab2 not opening a terminal.

Question: Is there a key combo to get into boot recovery mode (like with grub).
                 So I can mount a partition and edit the file.


Self-Bashing:  Yes, I did it while in a meeting and "quickly" changing sth. And of course I turned off sshd.
                        I have the UART but would love to avoid the serial console setup, or sd-card boot.


THX,
and I will promisse not to edit init stuff again while doing sth. else
