IMPORTANT COMMENT:
If remote host keys are changed, then
export GIT_SSH_COMMAND="ssh -i /opt/app/tools/atbupdate/.keys/id_ed25519_ptuConfig"
git pull
leads to the following warning/error message:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:vOD5jF2hglGktqLhK9ABxfEjwEgIK68/v9erdT05NDQ.
Please contact your system administrator.
Add correct host key in /home/root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/root/.ssh/known_hosts:1
Password authentication is disabled to avoid man-in-the-middle attacks.
Keyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.
Agent forwarding is disabled to avoid man-in-the-middle attacks.
X11 forwarding is disabled to avoid man-in-the-middle attacks.
Already up to date.
This first part is from ssh itself, and could not be fetched easily, as this
process is gone when git itself starts.
Only the last line is the git message.
