Just to give a short update of the current work of yesterday:
I moved the OpenPetra Website, Wiki and Forum to a new server. This was quite easy, because I could just move the LXC containers.
I also moved the workstation01.solidcharity.com (see Hosted Development Workstation) to a new server, with now much more RAM available (16 GB). I also upgraded it to Ubuntu 14.04. The home directories and logins of all existing users should still work fine.
Then I created the Linux packages for Uncrustify and Nant, so that we don't need to use the mono-openpetra repository anymore, but can use my mono-opt repository for the development of OpenPetra on Linux.
