might also need to look at the foreman-installer settings depending on how “custom” you want to make it:
–foreman-proxy-plugin-remote-execution-script-local-working-dir
–foreman-proxy-plugin-remote-execution-script-ssh-identity-dir
–foreman-proxy-plugin-remote-execution-script-ssh-identity-file
Any wrong moves here though and you will start to break things so be careful and snapshot before
