This is actually an nginx reload, not a restart.
Reload systemctl before enabling & starting new units.
Use `sed -i` properly in 'no known_hosts conflicts'.
Write custom path config to /etc/environment. (Hopefully temporary.)
Use double-quotes; /etc/environment needs the literal full path.
Also enable the ISO-8859-1 encoding for the chosen locale.

This seems to be required in order for the locale to be generated.
Wasn't ISO-8859-1 at all; it just needed a newline.

(Added Fancypath#puts to babushka in order to UNIX properly.)
Restart sshd properly on arch.
We have to wait for a moment after restarting services on arch.
No need for systemctl's '--system' here.
The nginx master should run as root.
Messy: make sure the nginx systemctl script is up to date.
