httpd_vhost.conf generation

How is this file generated ( /etc/httpd/conf/extra/httpd-vhosts.conf )?

I see no httpd-vhosts.conf in /usr/local/directadmin/data/templates, just httpd.conf.

Reason I ask is, obviously, when I upgrade apache & rewrite_confs, my (hostname) SSL cert stuff reverts and looks to self-signed cert paths.

Thanks.

Note: Half asleep, posted in wrong section, derp.

It's in /usr/local/directadmin/custombuild/configure/ap2/conf/extra, if you'd like to customize it, place it under /usr/local/directadmin/custombuild/custom/ap2/conf/extra.

Thank you.
