    Insert your SSH public key into "/etc/tinyssh/root_key", e.g. using
    "cat ~/.ssh/id_ed25519.pub > /etc/tinyssh/root_key".

    If you want to use the same host keys as your OpenSSH installation
    (only ed25519 for now), install tinyssh-convert or tinyssh-convert-git
    BEFORE rebuilding your initramfs. Or, if you already have keys generated,
    remove either the /etc/tinyssh/sshkeydir, or the ed25519 public and secret
    keys from that dir, in order to use OpenSSH keys. This hook will not overwrite
    existing keys either OpenSSH's converted or tinysshd-makekey created.

    Afterwards add the "tinyssh" hook after any networking hook (netconf/ppp)
    and before any hook provided with the mkinitcpio-utils package in the
    "HOOKS" array in "/etc/mkinitcpio.conf". Finally rebuild the initramsfs
    ("mkinitcpio -p linux").

post_remove() {

    the initramfs ("mkinitcpio -p linux").
