How do make junest programs use the SSH command of the host?

[NightMachinery]

I have installed emacs using junest. When I want to push my git repos, if I don't install:

pacman -Syy --noconfirm openssh

I'll get this error:

error: cannot run ssh: No such file or directory
fatal: unable to fork

When installing OpenSSH using the pacman command above, I get lots of errors, but it seems the installation succeeds anyway:

But the junest SSH cannot use my public keys in ~/.ssh, so it cannot access my Github repos. How do I solve this problem? I see two solutions:

1. Somehow make emacs use the host SSH command.
2. Copy my private/public keys somewhere that the junest-installed SSH can find them.

I tried doing this:

d="${HOME}/.junest/home/$(whoami)/.ssh"

cp -r ~/.ssh "${d:h}"
chmod 700 "${d}"
chmod 600 "${d}"/*(.DN)

But I get this error:
