Since no one else piped up, for now I've setup build.squeak.org to point to Jenkins. We can always add something else or change this easily enough. I left squeakci.org as an alias. Of course if that domain name is allowed to expire we should remember to remove that.
Since our servers tend to host a number of services under various hostnames we have found it useful to utilize the sites-available and sites-enabled directories under /etc/apache2 and avoid modifying the apache2.conf. The idea is to create a file in sites-available with the information necessary for a specific website. Then to actually make it work create a symlink in sites-enabled which points to the file in sites-available. Run sudo apache2ctl configtest to be sure that no mistake was made, then run sudo apache2ctl graceful to have apache reload it's configuration files and make the changes take effect. Something similar can be done with mods-available and mods-enabled once we find the need. One of the benefits of this system is that if there is a problem and one of the config files is suspected then you can temporarily remove it from the configuration by simply deleted the symlink and having apache reload the config. The configuration text remains and you can simply relink it when ready (and have apache reload again).
I went ahead and modified the config on box3 and setup such a file for build.squeak.org.
