Yea, that would cause the script to exit with a warning.

Thanks for the tip, I'll have a look at what is available.

That might be a result of bootstrap-x0 not running, we change the host
name there to be schoolserver.

Can't find schoolserver, related to the above failure to change the
hostname.

I'd just rename /etc/httpd/conf.d/pathagar.conf and retrying to restart
apache as a quick fix.
