Ran the whole process from script to completed builds again on Jenkins3 this morning, and all worked well, so I figure we're ready for the next stage. Wrote up the instructions and provided the script on the TEI Wiki, then set about preparing to build our proper VM for deployment. Initially we thought we'd do this using Remastersys to create an ISO for the full server install, but that failed -- the ISO wouldn't boot -- so we're going to take the same approach on our proper VM as is detailed in the wiki page. GN is arranging with sysadmin for the VM to be provisioned.
