SSH-Agentd Ansible role
-----------------------

This role create service and environment for managing ssh-agent service with
systemd.

Note that for exporting SSH_AUTH_SOCK in your session, you need to parse
fnvironment file in `XDG_CONFIG_DIR`. Here is an example for zsh, i put this
little snippet in my `.zprofile`:

```zsh
for file in ~/.config/environment.d/*.conf
do
    while read -r line
    do
        varname=${line%=*}
        value=${${(e)line#*=}//\"}
        export $varname="${value}"
    done < $file
done
```
